As early as the 1970s, the yurt is romantic fashion thing, and rage, Audrey Hepburn, appear together in people’s eyes, in “Roman Holiday” and “Breakfast at Tiffany” in film, we can witness to the “frog” style. Deeply buried deep in the eyes of large lenses, the special and personalized. When the trend of the wind once again return, a large frog glasses and return to fashion of the T station. 2006 T-station we can see the “yurt” in the most frequently appearing on the scene. Now, the South Korean star Bae Yong Joon, Hong Kong superstar Andy Lau, Tony Leung, Oscar movie Pearl Harbor is Ray-Ban sunglasses RAY BAN’s favorite frog. Polarized sunglasses on the damage of UV radiation on the human body, has a “cumulative”, that is exposed to the sun more time passes, the greater the damage of UV rays. United States has a statistical report, a lifetime of exposure to ultraviolet light, of which 80% was in the eighteenth before the age of sunlight exposure accumulated, thus avoiding the UV damage, we must start from childhood on. Parents should teach children correct ideas, to develop an early age the habit of wearing sunglasses to reduce the cumulative UV damage in the eye. Selection of sunglasses, do not think that the darker the lenses, the stronger the effect of UV. On the contrary, the deeper the color so they will become larger the pupil, unless the safety of the anti-UV lens, the more eyes to the light of UV, resulting in the injury will be more powerful. It is best to make sure the lens can effectively prevent more than 99% of the ultraviolet (UV, including UV-A and B), while both the polarization characteristics, so as to eliminate glare (glare is reflected from a certain angle of light to the eye will temporarily to see what people do not know), polarized glasses, polarizing angle is more theoretical. To meet these stringent optical requirements, responsible manufacturers often have to invest huge sums of money, personnel and equipment to design and produce it. Pros and cons of market quality sunglasses varies greatly, the price is also a world of difference, because that in here! To avoid the eyes from UV damage, of course, necessary to minimize exposure to strong sunlight, under, in particular, 10 am to 2 pm between the time period in direct sunlight the Earth’s surface, the highest UV intensity. Especially those by the concrete, snow, beach or water surface reflectance from the ultraviolet, are the most powerful, causing the eyes of the greatest damage, but it is the most easily overlooked. Therefore, to place a long time in these activities, remember to wear appropriate polarized sunglasses. ¡ô polarized sunglasses principle: natural light (non-partial Aurora), in fact, will move towards a specific direction by the shock wave formed, and is reflected or scattered light has usually prefer a particular direction, which is why polarized sunglasses can reflection from the roof or pool filter to the sun’s sake; natural light filtering through the polarized lenses, you can make only one direction of the light through the first light that is polarized to polarized lenses, the only allow light through in one direction (visible light). Polarized sunglasses is to use this feature to block harmful rays, as sunlight is to touch any object, whether due to natural reflection or refraction will produce harmful glare, polarized sunglasses can completely absorb these can cause glare and eye damage ¡ô generally light polarized sunglasses sunglasses with a comparison: the general use of sunglasses only reduce the role of light, because light can not be filtered lenses in general, we can only reduce the glare, the intensity of ultraviolet light, etc. , and can not completely block these harmful light, so its function is to reduce damage to the eyes, but generally the biggest advantages of sunglasses is epidemic good. Polarized lenses with polarized due to the nature, it can be completely blocked due to scattering, refractive, reflective, and other factors caused by the glare. Can also harmful to the human eye completely block ultraviolet light, long-term activities of people in bright light, the eye is not easy fatigue, achieve real protection functions, and make things more clear to see, three-dimensional. ¡ô polarized sunglasses feature: life, there are too many harmful rays will light, especially sunlight; the sun comes out where there is light: visible light, infrared, ultraviolet, three (as shown in Figure 5 . ) Them to ultraviolet light on human skin, eyes, etc. . . , causing serious injury; released by the sun’s rays in IR (Infra-red) IR (750mm) above, visible light (Visible light lay) (310 ~ 780nm) ; UV is divided into UVA, UVB, UVC (310nm) above, glaucoma (Blue light) which UVA, UVB, UVC light is harmful, if prolonged exposure may cause physical damage, UVB is a serious visual impact, ( Tanning Ray) is a burning light black skin, eyes will absorb most of this so be sure to block the UVB light source out of this. Polarized sunglasses as a function of the light polarization, so that all can block out the harmful rays are not affected by visible light, eye protection can really function. ¡ô the application of polarized sunglasses: polarized sunglasses because it can block 100% of harmful rays, so it can be applied: 1. Medical: eye surgery, you need a full range of protection, polarized sunglasses are the best choice. (2) outdoor activities: such as skiing, fishing, water sports, etc. , are required to completely block the harmful rays of the sun glasses to avoid eye injury or fatigue. 3 goggles ¡ô types of polarized sunglasses: So how to choose polarized sunglasses it? The polarized sunglasses in different colors, each with different characteristics. Pink or red of the lens, in the glare of a very strong case, you can enhance the contrast and sharpness, very suitable for water sports and snow activities in use. Brown or brown of the lens, because the color can enhance the contrast, so to become the first choice for driving the lens. Amber, yellow or orange of the lens, is ideal for wear when it is cloudy, you can have a very clear and the vision, but not suitable for use under the sun. Gray or dark green lenses, depending on the material can retain most of the original natural color, is a good choice. Sunglasses are not only required to wear in the summer before, in fact, throughout the year must be used. To wear sunny, cloudy have to wear. Do not think that a cloudy day the sun is not strong, the weather is not hot, to be taken lightly, unwittingly but more harmful ultraviolet radiation. Therefore, even cloud-of cloudy, still have to refer to the UV Index forecast, a good sunscreen preparations. Sunglasses maintenance tips 1, if Lo Si Song, please get the optical shop customers in a timely manner, timely tighten, otherwise the lens is easy to fall to the ground to play broken. Do not dispose of. 2, cosmetics or cosmetic agent with the chemical composition of cosmetic products, easy to fade frames, please use the special glasses, clean cloth or paper. 3, most of the eyes is to start with the left foot slightly off the mirror to put, if you put off hard from the right first, the frame itself will lead to imbalance, skewed, resulting in after you are not comfortable to wear. 4, in order to play the correct function of glasses, the optical center of the lens for your eyes to do in the area, wear the correct location. 5, wear glasses to take with one hand, easy to frame deformation.

Do not touch the lens with hard objects, not hand-grease smear the lens, the lens with a clean cloth sheet, reducing lens wear. 8, not convex lens toward decentralization. If not, try to put the eye box, if not wearing glasses when the glasses with a lens cloth bag and put in the mirror box, so as to avoid damage.
