Sunglasses,oakley asian fit sunglasses outlet also known as sun mirror, for shade purposes. People often rely on the sun to regulate the flux adjust the size of the pupil, when the light intensity more than the ability to regulate the human eye, it will cause harm to the human eye. Therefore, outdoor activities, especially in the summer, many people are using to block the sun visor mirror to reduce eye fatigue caused by regulation or light stimulation caused by the injury. Contents Introduction to the basic functions to prevent the sun’s ultraviolet radiation exposure to prevent light exposure to prevent glare to eliminate specific frequencies of light use classification classification classification of sunglasses lens color lens types and their respective characteristics of the market principle structure stained polarized specular reflection scratch resistant lenses injury UV protective layer anti-reflective coating coating technology indicators vertex deviation prism light transmittance (¦ÓV) average transmittance color traffic signal transmittance limit impact of advantages and disadvantages of using common sense logo sunglasses purchase recommended maintenance syndrome, four kinds of sunglasses fashion sunglasses sunglasses must not wear sunglasses purchase method of matching the three points cited ideal sunglasses should have an important condition for the basic functions to prevent the Introduction to ultraviolet radiation in sunlight to prevent light exposure to prevent exposure to eliminate glare use of specific frequencies of light classification classification classification of sunglasses lens color lens types and their respective characteristics of the market principle structure stained polarized specular reflection scratch lens coating Anti-reflective coating UV coating technology indicators vertex deviation prism light transmission ratio (¦ÓV) average transmittance color traffic signal transmittance limit signs advantages and disadvantages of using common sense impact of maintenance sunglasses buy sunglasses syndrome proposed four kinds of sunglasses do not be vulgar nightmare of criminal «Ñ Chong Flute “defended pepper ¨Ò ýÑ ¡Å rinse «Ñ Chong file ªµ Chu Li Na ý´ milk «Ñ cave Yun Chong Fu trouble killing polyester ¦¸ magnesium plaque ªÌ trampling þÕ About Sunglasses hoop edit this paragraph is a strong incentive to prevent sun damage caused by the human eye vision health insurance sunglasses supplies, as people’s material and cultural level, but also as a cosmetic or sunglasses reflect the personal style of special accessories. As the sun reaches the earth’s surface contains ultraviolet light, the human eye’s cornea and lens are the most susceptible to UV damage to the eye tissues, and the “cataract” is closely related eye diseases. Due to environmental damage to the ozone layer, and an increase in people’s summer outdoor activities, UV damage to the human eye can not be ignored. Wear sunglasses to protect eyes from UV damage better way, but pay special attention to the choice of sunglasses. In accordance with the provisions of international standards, are classified as personal eye protection sunglasses supplies areas as wearing sunglasses in the summer, the main function is to block the glaring sun. However, the international standard sunglasses again subdivided into “fashion mirror” and “general purpose use the mirror. ” Standard of “fashion mirror” of relatively low quality requirements. Because “fashion mirror” the main highlight is the style, the wearer focus is decorative, rather than protection. Standard of “general purpose use the mirror, ” the quality requirements are more stringent, including UV, and refractive error and the prism of the indicator. Edit this paragraph the basic functions of a pair of sunglasses looks very simple, that is, a plastic or metal frame, there are two colored glass or plastic film. What could be more simple sunglasses add it? In fact, the two glass lenses can produce a lot of difference when you use sunglasses, these differences will have a great impact on you. In this article you will learn all kinds of differences do exist between the sunglasses. A pair of good sunglasses must have the following four functions: to prevent the sun’s ultraviolet radiation ultraviolet light can damage the cornea and retina, high-quality sunglasses can completely eliminate the UV radiation. To prevent light exposure when the eye receives too much light, it will naturally shrink the iris. Once the contraction of the iris to the limit state, then people need to squint. If the light is still too much, such as the snow reflected sunlight, will produce damage to the retina. High-quality sunglasses can filter out up to 97% of the eyes to prevent light damage. Prevent glare surface exposure of some, such as water, can reflect a lot of light, and this will disrupt the line of sight produces the highlight or hide objects. High-quality sunglasses can completely eliminate the use of such a glare polarizer technology, we will introduce later polarizing technology. Eliminate specific frequencies of light certain frequencies of light will be blurred vision, while other frequencies of light can enhance the contrast. Choosing the right color for the sunglasses, making it in certain circumstances get better results. If the sunglasses do not provide UV protection, it will give you more exposure to ultraviolet irradiation. Cheap sunglasses filter out a portion of the light, causing your iris to open to receive more light. This also would allow more ultraviolet radiation to enter, increased ultraviolet radiation damage to the retina. Thus, a variety of sunglasses, there is a difference between really. For a particular use of the environment, the selection of suitable, high-quality sunglasses will provide you with maximum protection. [1] Edit this paragraph classification purposes Sunglasses can be divided into shade by use of a mirror, light-colored sunglasses, and three types of special-purpose sunglasses. The so-called mirror shade sunglasses, suggests that it is for shade purposes, people often rely on the sun to regulate the flux adjust the size of the pupil, when the light intensity more than the ability to regulate the human eye, it will cause harm to the human eye. Therefore, outdoor activities, especially in the summer, many people are using to block the sun visor mirror to reduce eye fatigue caused by regulation or light stimulation caused by the injury. Light-colored sunglasses for blocking sunlight than shade lens, but its rich colors, suitable for use with various types of clothing with, has a strong decorative effect. Light-colored sunglasses because of its rich colors, styles, by the young people of all ages, women’s fashion is fallen in love with it. Special-purpose sunglasses block the sun has a strong feature, common on the beach, skiing, hiking, golf and other outdoor sunlight more strongly, its UV performance and other indicators have higher requirements. Different groups of people, depending on the preferences and different uses to select the sunglasses, but the most fundamental thing is to protect the wearer from safety and vision does not damage the basic principle. Reduce the light stimulation, visual clarity without distortion, anti-UV, no distortion of color recognition, accurate traffic signal recognition, should be the basic functions of sunglasses. If the function defects, ranging from the role of loss of sunglasses, weight will produce dizziness, eye soreness and other symptoms consciously meet, and sometimes slow to respond, argue, and walk visual color illusion inequality symptoms and lead to accidents and so on. So I chose to focus on style sunglasses can not just ignore its intrinsic quality. The classification of sunglasses lens sunglasses lens types can be divided into: anti-reflective protective lenses, color lenses, color coated lenses, polarized lenses and photochromic lenses and other five. 1 anti-reflective protective lens: This lens is coated with a thin layer of magnesium fluoride to prevent light reflection, so you see things more clearly and without light interference. To test your sunglasses really use anti-reflective protective lenses, glasses can be aligned light source, if you can see the purple green reflective, it means the lens does have anti-reflection coated with a protective film. 2 color lenses: Also called “stained lens” is the lens production process, coupled with some chemical substances, so the lens showing the color to absorb specific wavelengths of light. This is the most commonly used lens sunglasses type. 3 coloring lens: This lens showing the effect of the lens with the same color, only made in different ways, it is the color applied to the lens surface, the most well known is the “gradient-like coloring the lens” color is above the deepest, and then gradually down light. Generally have more degrees of sun glasses lenses are coloring approach. 4 Polarized lenses: In order to filter the sun shines on the water, land or snow on the equality of the direction of the dazzling light, perpendicular to the lens to add a special coating, called polarized lenses. Most suitable for outdoor sports (such as: maritime activities, skiing or fishing) is used. 5 Lenses: It was also known as “sensitive lens. ” Because the lenses to add silver halide chemicals to the original colorless transparent lens, case of strong light, will become colored lenses, do protection, it is suitable for both indoor and outdoor use. Color of the lens types and their respective characteristics (1) piece of gray: gray lenses absorb any chromatography can be balanced, so watch the scene will darken, but will not have obvious color to show the real natural feel. A neutral color. (2) brown lens: filter out a lot of Blu-ray, can improve the visual contrast and clarity, punished, or in foggy air pollution case wear better. Generally smooth and shining surface of the block reflected light, wearing glasses can see the subtle part, is an ideal choice for the driver. (3) green lens: the absorption of light at the same time, maximize the green light reaches the eye, so there are very cool and comfortable feeling, suitable for people who use eye fatigue. (4) blue-gray lenses: gray lenses with similar lens with a neutral, but darker, higher visible light absorption. (5) Mercury lens: the lens surface using high-density mirror coating. Such lenses absorb more into the reflection of visible light, suitable for outdoor sports people. (6) yellow lenses: Strictly speaking, these lenses are not sunglasses, because it almost does not reduce visible light, but in the foggy and dusk, yellow lenses to enhance contrast, provide a more accurate video, it is also known night vision goggles. Some young people wear yellow lenses “sunglasses” as a decorative use. (7) light blue, light pink lenses: the same is decorative rather than practical lens. (8) dark green lens: absorb heat, bring the cool feeling, but the low light transmission and clarity, for the sun and wear, not wear while driving. (9) Blue Lens: Dai Taiyang sandy beaches and blue lenses can play, can effectively filter out the blue sea and blue sky reflected. Blue lens driving should be avoided because it will make us a confusion traffic signal colors. [2] Edit this paragraph markets many well-known brands such as Nike, Timberland, Gucci and Kenneth Cole, etc. , are the sunglasses as part of its product line. Many sunglasses manufacturers but also the characteristics of their products and special texture large increase publicity. According to the different properties and brands, sunglasses prices will be lower than U. S. $ 20 to several hundred U. S. $ between the float. In addition, the market there will be counterfeit. Shopping discount stores and flea markets in time, you will find vendors who sell counterfeit high-priced brands of counterfeit sunglasses, looks exactly the same appearance, but the prices are far lower than the real thing. When you buy sunglasses that do not choose counterfeit brand when you spend big money to buy just one brand, or the true nature of difference? Cheap sunglasses biggest problem is the lens production methods. They are simply ordinary plastic coated with a layer of color film. Even if these fake color and frame similar to the Oakley X-Metal Romeos or Ray-Ban Predators, but the actual lens is different. Edit this paragraph the principle of quality sunglasses is a very effective “light conditioners. ” Sunglasses can regulate external lighting, making it suitable for the human eye. The next section, we will introduce sunglasses sunglasses manufacturers using various techniques of light regulation. To better understand these technologies, we must first understand something about the light of knowledge. Light beam has a certain electromagnetic energy. Wave size is measured in wavelengths. Visible light wavelength range of 400 to 700 nm. The energy of light is inversely proportional to wavelength, the shorter the wavelength, the higher the energy. In visible light, violet energy of the largest red light energy minimum, and in the visible light spectrum is ultraviolet above. In fact, contains a lot of natural light in the ultraviolet. As the high-energy ultraviolet, ultraviolet can produce your cornea and retina damage. What is glare? The brightness or intensity is measured in lumens. For example, in the room, most of the artificial light intensity of 400 to 600 lumens. If the sunny outdoors, in a large range of brightness fluctuations, the shade of the brightness of 1000 lumens, and as such there is a large concrete highway where, brightness of 6, 000 lumens. 3500 lumens of brightness in the following, we feel very comfortable and the human eye. When direct light or reflected light to reach 4, 000 lumens of brightness, the human eye receives the light started to become difficult. When we try to see these very bright area, only to see the white flash, this is the glare. In order to reduce a large quantity of light entering the eye and cause discomfort, we began to squint. Once reaching 10, 000 lumens of brightness, your eyes because of the received light is too strong and begin to completely filtered light. Strong light in such a long time exposure can cause damage, leading to temporary or even permanent blindness. On a clear day, a large light reflected from the snow can be up to 12, 000 lumens brightness, if we have no protection in the case stare into the light will lead to “snow blindness. ” Visible to the human eye can detect light. We see the visible light emitted by the sun appears to be colorless, that is, we often say white. In fact, it is a combination of the frequency of a mixture of colored light. Spectrum in the visible range of a mixture of all the light shade is colorless, that is white. (For more information, see the light of the principle). We have two basic ways to see colors. One way is itself an object can be issued a certain frequency of light, for example, is one such neon colors shown; Another way is to absorb all the other objects in the frequency of light, but only certain frequencies of light reflected, or reflected a variety of frequencies light, a mixture of these light waves perceived color of light, for example, the object is coated with a paint color that was the case. For example, to see the yellow light, a way that is direct object the frequency of light yellow; Another way is part of the absorption spectrum in the blue light, reflecting red and green part of the light, mixed light after two people perceived as a yellow eye. Turning to the light with sunglasses on, the following three types of light is very important: direct light – just from the direct light source (eg sun) light directly hitting your eyes. Too much direct light will seem obscure the details of the surrounding environment, but also allows you to hard to concentrate attention. Reflected light – glare of reflected light are often based on the form. Reflected light is reflected from an object on the light reflected back to the eye. With direct light, it is strongly reflected light makes it difficult to perceive the details or look directly at an object. Snow, water, glass and white sand are good reflecting surface. Diffuse light – just after the bounce and diffuse a lot of direction towards the scattered light, so light does not seem that a particular light source. A typical example of diffuse light is the glow over the city. Difficult to determine for a single light source. In the absence of direct light, we can see things, this is the diffuse light of the credit. High-quality sunglasses can eliminate UV spectrum, reducing direct light, so that people feel comfortable, while the reflected light can eliminate or reduce (depending on reflector). An interesting characteristic of the light is polarized. When the reflection from some surfaces, such as water, the light polarization. Since the polarization properties of reflected light, polarized sunglasses can eliminate the reflection from the surface of the water, or similar surface the reflected light. Edit this paragraph structure stained lens sunglasses lens color lens can determine which parts of the absorption spectrum of light. Manufacturers use different colors to produce specific results using the effective sunglasses. 1, the color gray is a good general, the reduction of brightness, while its color with minimal distortion. Gray lenses provide glare protection, making it ideal for driving and general-purpose choice. 2, yellow, blue or gold to reduce the lens, while the other frequency to allow more light through the lens. Because a lot of blue light can bounce and scattered light, which can produce a condition known as blue haze of glare effect. In fact, the yellow part to eliminate the blue spectrum, which makes all objects appear bright and clear. This is why the sunglasses prevent snow blindness is generally yellow reasons. Perception of these colors will make the color a little distortion, and thus not suitable for this type of sunglasses color to identify those who need accurate color activities. 3, amber and brown are also good universal color. They can reduce the glare effect, in addition to ultraviolet light outside the molecule can absorb its unique higher frequency colors, such as blue. Studies have shown that long-term acceptance of near-ultraviolet light (such as blue and violet) radiation, is one of the risk factors of cataract. In fact, Sun Tiger has a special version called Blue Blockers, with the patent. Sunglasses with yellow lenses, as these will cause color distortion, but will increase the contrast and sharpness. 4, the green part of the lens to filter out blue light, but also to reduce the glare effect. In all color lenses, green lenses offer the highest contrast and greatest visual acuity, so popular. 5, in the context of green or blue, purple and rose-colored lenses can provide the best contrast of objects. Thus they are a good choice for hunting and water skiing. Many sunglasses manufacturers use a process called constant density to give the lens dyeing. This is the most old-fashioned sunglasses manufacturing process, the mixture of glass or polycarbonate materials have the same color. Thus this process in the manufacture of lenses, the lens color is inside. The layer of light absorbing molecules deposited on the surface of pure polycarbonate, is a staining method. Dyed polycarbonate lenses to the most commonly used method is to soak the lens in a special liquid containing coloring substance, the substance that will slowly be stain plastic absorption. If you make the color deeper, just soak in the liquid inside the lens to extend the time. Polarized light from the sun or artificial sources such as light bulbs, the vibration in all directions and spread. Whether the light is transmitted, reflected, refracted, or divergence, when the light is in one or more of the plane direction of the vibration, we say that light is polarized. Polarization can be naturally occurring, it can be artificially stimulated. Each time you observe the lake to see the glare is an example of natural polarization. Reflected glare from the lake through the lake is not able to “filter” of light, which is why even if the water is very clear, objects are not able to see the reasons for the lake. Polarization filter is usually coated by a layer of chemical film on the surface of a transparent plastic or glass made up. Typically, the compounds used in the molecular parallel between the natural. When they are evenly coated lenses, these molecules form a tiny lens, they can absorb all of the orientation with the same light. Forcing you to wear sunglasses most of the glare comes from horizontal surfaces, such as water and highways. When light reaches a surface, the reflected light will be polarized, the same direction and angle of the surface. Thus, a high level of reflective surfaces, such as lake levels can produce large amounts of polarized light. Therefore, sunglasses polarized lenses fixed at an angle, so that only vertically polarized light through the lens can be. You can use the following methods to observe this principle: wear polarized sunglasses, and then observe a horizontal surface, such as the car hood. Slowly tilt head to the left or right. You will find the glare from the surface of the eye as you adjust the angle becomes bright. Before buying, you can do a simple test to identify its authenticity. Find a reflective surface, and then took the sunglasses, through a lens to observe the surface. Slowly rotated ninety degrees to the sunglasses, observe whether the decrease or increase reflected glare. If the sunglasses are polarized sunglasses, you will see significantly reduced glare. Aspects of sunglasses when exposed to sunlight below, the color will darken to sunglasses or prescription glasses are called color glasses. Color glasses by Corning in the late 1960s developed by Transitions in the 1990s to promote the use. Lenses rely mainly on the principle of a special chemical reaction of UV. Lenses contain certain substances (such as silver chloride or silver halide) of millions of molecules. When there is no ultraviolet radiation, visible light can penetrate these molecules, while visible light is a general component of artificial light. But when exposed to sunlight, ultraviolet light, these molecules will go through a chemical process, so that their shapes change. The new molecular structure absorbs some visible light, so that the lenses darken. Shape change of the number of molecules would change with the change in UV intensity. Sunglasses when you come indoors, leave the UV irradiation, the chemical will occur against the corresponding changes. Suddenly left the UV irradiation, these molecules will be quickly restored to the original structure, thus losing the light absorption characteristics. Whether it is positive change or reverse changes in the speed of the whole process occurs very rapidly. In Corning, the 1960s produced PhotoBrown and PhotoGrey series, the lens is made of glass, evenly distributed throughout the molecule in the lens. When prescription glasses when using this method, it brings the problem will become apparent, because the different parts of the prescription lens thickness may change slightly thicker areas will be even more darker color. But with the growing popularity of plastic lenses, it has developed a new approach. Through the plastic lens soaked in a chemical bath, color molecules will be absorbed into the plastic lens of about 150 microns in depth. This new method is much better than a simple coating process, in which the coating process, the color molecules only 5 microns thick, so it can not provide enough elements to make the lenses darken. At present, the color industry leader in the Transitions lenses have plastic lenses that promote the spread of the adsorption process. Specular reflective sunglasses lenses can be as reflective as a mirror. The lens is coated with a layer of very thin reflective coating – As the coating layer is very sparse, so it is called half-silvered surface. “Half-silvered, ” the term molecular reflection from above the lens is very sparse, and their number is only about the lens to become opaque when the mirror half of the number of molecules. At the molecular level, reflective elements dispersed in the lens surface, forming a layer of uniform film, but only half the area of ? ? the lens is covered by the film. This half of the silver surface can reach about half of the surface reflection of light, and let the other half of the light directly through. Typically, the mirror coating is gradual, paint gradually change color depth from top to bottom. This can enhance the sunglasses from the top of the resilience of the light, while allowing more light into the goal from the bottom and the horizontal direction. This means that when you’re driving, sunglasses block the sun’s rays at the same time, also allows you to see the dashboard. Sometimes, the paint is a two-gradient, upper and lower lens maximum color depth, and the middle of the lens is clear. The key issue is reflective sunglasses coating is easily scratched. Obviously, manufacturers are now not able to successfully sunglasses in the reflection film coated with anti-scratch layer. Thus, anti-scratch layer is coated on the surface of the lens, while the reflective film is applied to the anti-scratch layer on top. Anti-scratch protection layer is a natural anti-scratch glass, but the vast majority of plastics are not. To solve this problem, manufacturers developed a series of methods, the surface coating layer of a transparent lens but solid film. Such film is diamond-like carbon and polycrystalline diamond sintered body composed of such substances. Through the ionization process, the lens surface to form a thin but very durable film. Anti-reflective coating sunglasses is a common problem appears glare, back to the glare of light hitting the lens on the back after he reflected to your eyes generated. The role of anti-reflective protective coating is to reduce the light of this lens reflex. Scratch-resistant protective layer with the same anti-reflective coating is a layer on the lens is very strong, thin film. Anti-reflective coating material between the refractive index between air and glass. This makes the film and the inner surface of the outer surface of the reflected light intensity is almost equal. When the film thickness of about a quarter wavelength of light, reflected from the film inside and outside surfaces, respectively, out of the light will cancel each other out through destructive interference, thus minimizing the glare you see. Anti-reflective coating is also applied to the refractive lens and the front surface of some sunglasses to eliminate glare produced by the lens reflection “hot spots. ” UV coating some of the most serious causes of eye diseases are: UV. According to a different frequency and wavelength, UV is divided into two categories: UV-A and UV-B. Eye as a natural protective mechanism, it is the eye’s cornea can absorb all the UV-B and most of the ultraviolet A. However, there are some UV-A will reach the lens of the eye. For a long time to absorb UV-A may lead to cataracts, cornea reach the retina through a small amount of UV-A can lead to macular degeneration, and macular degeneration are over the age of 65 resulting in blindness. Long-term exposure to strong UV light can cause eye cancer or actinic keratitis, which is the retinal burns. This often happens after a sunny day in the winter snow in the outdoor, snow reflect the sun glare, which is often called snow blindness. Sunglasses have a good UV coatings, UV radiation can be eliminated, you must make sure that your sunglasses filter out two kinds of ultraviolet light to one hundred percent. The label on the sunglasses the sunglasses should indicate to what extent can provide UV protection, and you need 100% protection. Edit this paragraph technical indicators vertex deviation sunglasses nominal vertex value should be 0. 00D, the deviation of the lens or lens manufacture and assembly of the frame does not match, are likely to produce sunglasses vertex deviation (ie, with either positive or negative vertex), if beyond a certain range, the wearer may feel visual distortion, it will seriously affect the health of the wearer’s vision. Corresponds to the GB10810. 1 “spectacle lenses – Part 1: Single-light multi-focal lenses, ” the national standard requirements of Table 1, the spherical vertex tolerance of ¡À 0. 12D; cylinder vertex tolerance of ¡À 0. 09 D. Sunglasses prism of the prism should be 0. 00¦¤, if the lens has a prism, it will produce a visual shift focus, if more than the standard allowable range, it may lead to binocular objects can not be one, or have a sense of the level of imbalance , increasing the wearer to adjust the ocular and optic nerve disorder, can lead to serious neurological disorder or adjustment have strabismus. Requirements according to GB10810. 1 Table 4, the prism degree of tolerance for the 0. 25¦¤. Light transmittance (¦ÓV) For light-colored sunglasses, the light transmittance of> 40%; for the sun mirror, the light transmittance in the range of 8% to 40%. Project is characterized by light transmittance function is an important indicator of sunglasses. China’s current standard here Sunglasses feature will be divided into three categories: sun mirror, light-colored sunglasses, and special-purpose sunglasses, while the European and international standards will be divided into five categories. Category is different from the use of different sunglasses. If the use of light-colored sunglasses for sun, shade the wearer will not get good results, such as strong sunlight for a long time in outdoor activities, the wearer will be under strong light stimulation and fatigue. Light-colored sunglasses general decorative role, or is not strong in the sun room and so on. On the contrary, in the room or do not need a place to wear sun block strong sun mirror, because the pupil will enlarge and produce excessive discomfort, fatigue and so on. In the sun mirror, the transmission is not suitable for smaller products or drivers to wear cycling, because the rider or driver’s road speed faster than pedestrians, transmittance is too low will affect their ability to respond. The average transmittance (UV spectral region) the average transmittance value is in the lens in the UV spectral range of the average transmittance of ultraviolet rays, the standard provides: a) 315nm ~ 380nm in the UVA band, the average transmittance ¦ÓSUVA should ¡Ü ¦ÓV; b) of UVB in the 290nm ~ 315nm band, the average transmittance ¦ÓSUVB should be ¡Ü 0. 5¦ÓV. In addition, the UVB band, the average transmittance of light-colored sunglasses should be ¡Ü 30%, sun mirror, the average transmittance should be ¡Ü 5%. When the sunglasses meet this requirement, reached the minimum protection requirements, that block the light, while also blocking the corresponding amount of ultraviolet light, wear sunglasses at least not to increase the acceptance of the amount of UV light (wear sunglasses, will reduce the flux into the human eye, causing the wearer pupil increase, in the same external conditions, if the sunglasses can not block the appropriate amount of UV light, the eye will accept more than not wearing sunglasses UV). In November 2006, the formal implementation of GB10810. 3 “spectacle lenses and related products Part 3: Transmittance specifications and measurement methods”, defined as the UV transmittance of the lens sunglasses may not exceed 5%. Sunglasses have UV capabilities, generally have the following explicit way: a) marked “UV400″: This means that the lens on the UV cutoff wavelength of 400nm, that is, its wavelength (¦Ë) in the 400nm spectral transmittance of the following maximum ¦Ómax (¦Ë) is not greater than 2%; b) marked “UV”, “UV”: This means that the lens on the UV cutoff wavelength of 380nm, that is its wavelength (¦Ë) in 380nm below the maximum spectral transmittance ¦Ómax (¦Ë) is not greater than 2%; c) marked “100% UV absorption”: This means that lenses with 100% UV absorption features, that in the ultraviolet intervals not greater than the average transmittance of 0. 5%. Above-mentioned requirements sunglasses, is the real meaning of the ultraviolet protection sunglasses. Anti-UV sunglasses performance is an important indicator of whether the anti-UV sunglasses feature, we can not distinguish with the naked eye. China’s current anti-UV performance standards for products that only the basic requirements, that the wearer safe. Protection mainly by the production companies to make explicit commitments, but not all sunglasses have UV capabilities, as a consumer to identify whether the product has anti-UV function, only the factory’s express commitment to the product as the sole reference. Limits of simulation through the lens color yellow and green traffic signal observed and the observed average daylight through the lens, the standard provides that: the corresponding color coordinates should be in the chromaticity diagram (QB2457-1999 Figure 1) in the corresponding area. If the measured color coordinate value of color beyond the prescribed limits of the region, will lead to confusion of traffic signals, traffic accident risk is one. Traffic signal transmittance through the lens observed red, yellow and green traffic signal, the standard specified in the corresponding traffic signal for transmission ratio: the red signal should be ¡Ý 8%; of yellow and green signals should be ¡Ý 6%; if colored traffic signal transmittance is too low, then reducing the recognition of the signal, but also the risk of traffic accidents. Signs according to QB2457-1999 requirements of the logo, each pair of glasses should be the standard code indicating implementation (QB2457, etc. ), category (sun glasses or light-colored sunglasses, etc. ) and production and the name and trademark. Categories marked in the selection of sunglasses for consumers according to use and buy the right places. Impact resistance for the express protection or compliance with ANSI (American National Standards) of the lens, it must be able to withstand 16g ball from the free-fall height of 1. 27m rather than the impact of fragmentation. The index is a minimum requirement for protection glasses. If the lens has a protective function explicitly, but pass the standard, there are likely to mislead consumers from unsafe situations wearing a pair of glasses that are safe if an accident occurs, will directly endanger the consumer’s eyes. [3] Edit this paragraph the advantages and disadvantages advantages: 1, nicely decorated, 2, block eye defects, 3, protect the eyes (contact lens wearers to prevent evaporation) 4, protect eyesight (anti harmful rays) Disadvantages: Quality does not good and easy on the eye lens damage, in addition to sunglasses is to protect the mirror, or a few shortcomings. Edit this paragraph susceptible to improper use common sense to wear sunglasses, eye, cloudy, light, dark room and so the case does not need to wear sunglasses. Some people, regardless of where, regardless of the strength of sunglasses, sunlight, even in the dusk, evening, and in movies, television, also wearing sunglasses, which will inevitably increase the burden on the eyes adjust, causing muscle tension and fatigue, vision loss, blurred vision, severe dizziness and other symptoms will appear. For lack of development of the visual system of infants, children should not wear sunglasses. In addition to glass sunglasses, other wear sunglasses lens materials is not high, users should always pay attention to the surface of sunglasses, when worn affect clarity, should be replaced. Edit this paragraph the maintenance of dazzling sunglasses sunglasses let you active in the sun, good freedom. In fact, sunglasses resist the sun, can not stop the pollution damage, so be careful care, lest face embarrassing Oh. Maintenance methods like sun glasses spectacles general maintenance, cleaning, closed stack, storage should be a habit. But sunglasses are often Tuotuo Dai Dai, believe it will scratch, so there are some small details to remind you: sun glasses tainted adhesion, it can not use nails to pull, could easily scratch injury the surface. Do not wear sunglasses, many people will easily hang in the head, collar or pocket, range of motion at this time the body can do much to avoid tearing or crashed. Perhaps some will put in handbag, recommend that you first put in hard glasses case, and then into the bag, so as not to be the key, comb, copper and other small things wear lenses, or catching lipstick and other cosmetics. Car owners are wearing sun glasses, do not wear often easily on the dashboard or seat, this is a very bad habit, hot weather will not a prototype baking sun glasses, in particular, especially the plastic frame , it is best to take off, or collection box placed in the glasses. Whether you will be where the collection of sunglasses, be sure to remember that the mirror should be facing up. Edit this paragraph on how to buy buy sunglasses recommended different people, depending on the preferences and different uses to select the sunglasses, but the most fundamental thing is to protect the wearer from safety and sunglasses do not damage the visual basic principle . Reduce the light stimulation, visual clarity without distortion, anti-UV, no distortion of color recognition, accurate traffic signal recognition, should be the basic functions of sunglasses. If the function defects, ranging from sunglasses would not achieve the role of weight will produce dizziness, eye soreness and other symptoms consciously meet, and sometimes slow to react, argue the color visual illusion and walk the symptoms and lead to unequal traffic accidents and so on. So I chose to focus on style sunglasses can not just ignore its intrinsic quality. High-quality Polaroid TAC polarized lens, polarized lenses protect your eyes from reflected light of the people hurt, can enhance the visual contrast outdoors, especially when driving, polarized lenses can be reduced glare, stray light. Summer is the world of sunglasses, fashion, beauty, radiation protection, these features make it more like wearing sunglasses, but experts point out that the time to choose sunglasses doubly careful not only concerned with style, while ignoring the quality of their sunglasses. Four do not wear sunglasses failed: 1, anti-UV sunglasses unworthy of the name. Good sunglasses polarized lenses can block more than 99% of ultraviolet rays. Wearing UV sunglasses with poor function, eyes like things seen in the darkroom, when the pupil becomes large, the residual will be a substantial injection of ultraviolet instead of the eye, the eye hurt. 2, the rate of failure of sunglasses perspective. Wear, will have a traffic signal recognition barriers, can easily cause accidents. 3, the category did not identify the sunglasses. Sunglasses are generally divided into three categories, namely, the mirror for the sun shade for decorative mirrors and light-colored waterproof surface for anti-radiation, snow blindness, or the special glasses. 4, against the performance does not meet the requirements of the sunglasses. By external shocks in the lens easily broken, fragments will form a deadly hurt people’s eyes. Experts advise consumers to buy sunglasses should try to choose high-quality polarized glasses. Consumers buy sunglasses is important to note the following points: 1, first of all to know the purpose of purchasing sunglasses from the above description of several types of sunglasses, we know that different types of sunglasses has a different application occasions and people. We want to buy sunglasses, first make sure your purchase is for the purpose of shade, with clothing or for decorative role? In addition to UV sun there than functional requirements? The safety performance of the lens there any special requirements? Only clear these aims, combined with style and worn on my face the practical effect, to buy a suitable sunglasses. 2, to learn to read the product identification is not all sunglasses have UV features a standard to meet the basic requirements of sunglasses, can only say that while there is no light in the block more UV light through. If a pair of sunglasses can block light and can not block the same amount of UV light, in terms of the wearer, will accept more than not wearing sunglasses, UV light (wear sunglasses, will reduce the flux into the human eye, resulting in wearers pupil increase). Counter in a store selling sunglasses, the lenses on the tag or packaging are generally obvious uv380, uv400 and other similar signs, as in the clothing label on the fabric composition, consumers must purchase closer look. (1) the identity of the UV features a pair of sunglasses have UV features, we can not distinguish with the naked eye, factory express commitment to the product to consumers with a protective function is the only reference to sunglasses, we can Some products, such as labels and glasses to see the positive: “100% UV”, “UV400″, “block all UV” “UV” and express identity. UV wavelength is between 200nm ~ 400nm in the sun’s rays, including three types: UVA wavelength of 315nm ~ 400nm, UVB wavelength of 280nm ~ 315nm, UVC wavelength of 200nm ~ 280nm. The sun’s rays reach the earth’s surface (290nm ~ 2000nm) in about 13% of ultraviolet rays, UVA which accounted for 97%, UVB accounts for 3%, UVC close to 0. UV damage to the human eye is mainly determined by the wavelength of ultraviolet light, radiation time and radiation intensity of the human eye’s own defense mechanism and the strength of the cornea, the lens is the most common ocular tissue damage by ultraviolet radiation, solar keratitis and corneal endothelial damage , with the most daylight of cataract is related eye diseases. In order to protect the health of the eyes, you can choose a function of the lens made of UV sunglasses, try to eliminate the UV below 400nm. (2) the identity of the security performance with safety sunglasses, the lenses used, such as PC tablets, TAC and other impact-resistant lens material, and instructions on the label are often marked with “There is impact resistance, ” ” certified by the U. S. FDA, “” meet the highest standards in Europe and America, “and so on, if the product can achieve the requirements on the identification, motorcyclists, drivers and other special requirements on the safety of consumers is a good choice . Commitment on the product logo, consumers must learn to protect themselves, the label or instructions or keep it, or let the business stated in the invoice, in the event of disputes, lack of evidence will not be passive. 3, the intrinsic quality of the lens must identify the basic skills (1) the degree of lens should meet the requirements for plain lenses and should not affect the vision of the optical flaws. Simple identification method can be placed in front of sunglasses, observe distant targets through the lens, such as window frames or door frames, etc. , and then move back and forth up and down the glasses, the goal should not swing and wave-shaped deformation. (2) The color of the lens can not be partial, the color of the surrounding environment should be made without distortion, sharp edges of objects in different color lights have a valid identification ability. The choice of lens color depth, depending on the required activities for the place, depending on light sources and for different occasions, will affect the color of the lens shading effect. For sunglasses can effectively block the Xia Jiqiang light, the color of glasses due to sufficient depth, but those who ride or drive, do not choose too dark lenses. Approach a selection of sunglasses, with the face, skin color, work environment, dress match; two, put on later to see objects more clearly do not faint; third, effectively prevent the ultraviolet, with uv380, uv400 other similar location identification; 4, well have matching sunglasses case, lens cloth, tags and so on. Myopia matching sunglasses sunglasses on the market now, and more generally for plain, matching sunglasses and how myopia, senior optician has recommended the following: First, with the use of contact lenses and sunglasses. The first contact lenses to get a good visual acuity, and can freely choose a sunglasses like. Second, the use of sunglasses, clip, clip it out in myopia, simple inexpensive, but the clip choice of styles, colors, small, less beautiful. Third, the use of resin stained lenses, sunglasses made of myopia. Colored glasses, but not suitable for indoor wear, so an additional prepare ordinary glasses. Fourth, the use of photochromic lenses. German Zeiss, Essilor, France, Japan, Hoya resin or glass color lenses, have good color effect and reliable optical performance, and a pair of glasses can be both indoor and outdoor, very convenient, but more expensive than the lens you. Fifth, with a set of mirrors, that is, outside the glasses, there is a circle completely consistent with the mirror lens sunglasses set by the magnet fixed to the frame the frame, although the aesthetics greatly changed over the clip, but an increase of glasses the weight. Five kinds of programs to choose according to their own consumers. If you have a habit of wearing contact lenses, with most people, like you can not directly buy sunglasses degree, if not the habit of wearing contact lenses, you have to be configured separately with prescription lenses. Edit this section to wear sunglasses summer sunglasses syndrome more people up, some of the glasses are put on the color lenses, eye wear all day long. And some young people to pursue fashion, the sunglasses as an ornament, regardless of where, separated from the eye lens, the passage of time will cause vision loss, blurred vision, will have a severe headache, dizziness, blurred vision and can not be long as the and other symptoms. Medical experts of the above symptoms as “sunglasses syndrome. ” This reflected a variety of symptoms of discomfort, such as early in the area around the eye near the nose, a clear sense of numbness and tingling, breathing symptoms become more pronounced, much like the common cold, and feel like a small insect crawling away in the face maxillary gingival numbness, discomfort incisors, local skin inflammation caused by poor blood circulation, eye soreness, vision loss. Anatomy and physiology that has a small hole in the bottom of the eye, called the infraorbital hole, this hole has an important nerve branches, infraorbital nerve is the trigeminal nerve. It is located between the eye fissure crack in the mouth and nose of the skin, head sensory function. Because the weight of sunglasses and focus the lens ring infraorbital nerve compression, nerve distribution area will lead to discomfort, wear sunglasses more in 2-3 weeks later. Prevention sunglasses syndrome, first to select the correct and rational use of sunglasses. Do not choose large glasses. Because such frames are mostly imported foreigners face design is based, and our most adults is less than double the distance the pupil large glasses imported from the optical center, wearing the glasses will greatly increase the regulatory function of the eye burden, damage to eyesight. The street stalls selling cheap sunglasses, made a very rough, the lens thickness varies, the color is not uniform, poor optical performance, easy to wear after the cause headache, eye pain, fatigue and discomfort, often wear sunglasses that bad, easily lead to vision loss. Secondly, as far as possible do not wear large sunglasses. When wearing glasses must be worn to shorten the time, picking Orbital mirror along with the palm of your hand, massage both sides of the nose 10-20 times, in the event of sunglasses syndrome, they should stop wearing. In addition, short-sighted people if you want to wear sunglasses, clip tool can be used while wearing glasses, sunglasses and myopia to wear color lenses, or myopia. Edit this paragraph four kinds must not wear sunglasses summer sunglasses in the world, fashion, beauty, radiation protection, these features make it more like wearing sunglasses, but experts point out that the time to choose sunglasses doubly careful not only concerned with style, while ignoring the quality of their sunglasses. Four do not wear sunglasses failed: 1, anti-UV sunglasses unworthy of the name. Good lenses that can block more than 99% of ultraviolet rays, and are identified with UV400 lenses can be 100% (99. 99%), UV-blocking. Wearing UV sunglasses with poor function, eyes like things seen in the darkroom, when the pupil becomes large, the residual will be a substantial injection of ultraviolet instead of the eye, the eye hurt. Better go to the store to buy or shop in the high-profile flagship store to buy or purchase. Certainly not a small stall on the purchase, although those sunglasses can block UV, but the lenses do not work in place, that is substandard, do not buy it because of cheap, poor quality of the eye will cause varying degrees of damage to the eyes. 2, the transmittance unqualified sunglasses. After wearing the sunglasses, will have a traffic signal recognition barriers, can easily cause accidents. All sunglasses, including a professional driving mirror, sport mirrors, mirror . . . . . . Fishing. (Except for myopia and reading glasses) for the simple identification method can be placed in front of sunglasses, observe distant targets through the lens, such as window frames or door frames, etc. , and then move back and forth up and down the glasses, the lens field of view of the target should not be a swing and wave-shaped deformation. 3, the category did not identify the sunglasses. Sunglasses are generally divided into three categories, namely, the mirror for the sun shade for decorative mirrors and light-colored waterproof surface for anti-radiation, snow blindness, or a special lens. If there is no product category identification, consumers are unable to correctly identify the use of sunglasses, affect the results. 4, against the performance does not meet the requirements of the sunglasses. By external shocks in the lens easily broken, fragments will form a deadly hurt people’s eyes. Frame material is also very important, generally plate, aluminum-magnesium alloy, pure titanium. Different demand requirements are not the same for the sun, have a special movement for movement’s polarized lens, polarized driving lens, polarized fishing mirrors, etc. , at time of purchase, ask the professional use of clear sunglasses. Experts advise consumers to buy sunglasses should go to regular stores to buy well-known brand; purchase should first try, and more wear before and after wearing the color change is obvious to see that after wearing sunglasses color distortion of objects is appropriate. Dai Taiyang lenses halo is why? If you bring sunglasses to go with the feeling dizzy, feet mirror may be too tight, not part of the nose pads arising from pressure, or the lens itself steradian, prisms and other parameters due to unequal. Phenomenon of colorful lens, in principle, has nothing to do with the dizziness, but may result in poor visual effects. Colored lenses may be due to the injection process when the degree of fluid problems or issues. Our glasses are normal stresses in the high-end glasses from China professional manufacturer, and is a long history of Taiwanese manufacturers. Should control in this area is good, but sometimes it is inevitable that undesirable phenomenon. After all, handiwork. 8 How much is the bending of the sunglasses with prescription, may also cause dizziness. Added: the perspective of most of the adjustable nose pads, dizziness, sunglasses are also most likely fail, you should stop wearing. The following non-quality problems caused by dizziness: ¡ô the first time, a friend to wear sunglasses, there will be individual dizziness phenomenon usually wear can be adapted over time, mainly with the relationship between the degree of sensitivity of the eye; ¡ô Second large frame sunglasses to wear a large arc of dizziness, it is because there is a certain degree of sunglasses, the greater the curvature, the greater the relative degree, a degree will have the optical center, a large frame is greater than the human eye from the optical center of the IPD , some people wear occurs dizziness. ¡ô There is also wearing sunglasses glaucoma dizziness, do not explain in detail here, the specific reasons can be to the local doctor. ¡ô light the dark when wearing sunglasses, sunglasses, light itself has weakened the role, this time wearing sunglasses, will result in increased intraocular pressure, and then place dizziness. Experts advise [6] is also not suitable for children under the age of long wear sunglasses, because their immature visual function reach adult levels, long wearing sunglasses may be the formation of amblyopia. Edit this paragraph fashion sunglasses purchase method of UV coating on the front section, we discussed the problem of ultraviolet radiation. UV radiation is a common concern, and we also need to consider some other more specific health problems. For example, if your eyes are sensitive to light, then you will want to use those to filter out the visible part of the sunglasses. In addition to providing ultraviolet protection, some sunglasses also provide infrared radiation protection. Sunglasses while playing a huge role in safety equipment. By reducing glare, sunglasses so you can more clearly see the surrounding environment. You may have noticed that most of the Highway Patrol are wearing sunglasses, sunglasses can help them to focus attention on an object, such as 121 kilometers per hour, a car, without the need for squinting. Performance and perception of some of the sunglasses are equipped with specific filters can reduce glare, increase contrast, and can even increase your depth perception. This makes them ideal for certain sports, such as beach volleyball, or for a specific job, such as Highway Patrol. Meanwhile, filtered harmful radiation, sunglasses can help you extend the time for outdoor sports, and will not be some negative impact. Italy dedicated anglers polarized sunglasses, polarized lenses because they can eliminate surface glare issue. So anglers can more easily see the depths of water, but also easier to find the whereabouts of erratic fish.
