-- 1. Photochromic lens could be used as the corrective lens and sunglasses lens at the same time. Since it has a high transmittance for visible lights when in the colorless state, the photochromic lens can be used as corrective lens absolutely. And in the sunlight, the glasses with photochromic lenses could be used as sunglasses. The combination of the two functions makes the lens convenient to use, which is the biggest advantage of the lens. What should be noted is that some people have not understood the photochromic lens completely and they believe that the lens can only be used in the hot summer as the lens of sunglasses. Therefore, the phtomochromic lens is usually promoted in summer. Actually, the photochromic lens is important to our eyes all year round for the UV rays are all relatively strong in the four seasons. Even at noon in winter, our eyes may be harmed by the UV rays and a pair of photochromic glasses (http://www.finestglasses.com/photochromic-glasses.html
) is the easiest and the most practical solution to this problem.
2. Photochromic lens could be used as goggles. It can be used in many special occasions like skiing, wayfaring, hiking, fishing, swimming etc. Due to the intensifier UV rays in these occasions where there are sno fields, high mountains and waters, the damage to the eyes can be more serious; and at the same time the clarity of the vision should be ensured, thus here comes photochromic lens to meet all the demands from all aspects.
3. Photochromic lens could also be used as an element of fashion. Apart from the function of blocking glare, the photochromic lens is very effective for beautifying. Therefore, used for fashion, the lens would have a promising future.
4. Photochromic lens could also be used for driving. Drivers would be disturbed by glare from time to time, and a pair of photochromic and polarized glasses can solve all the problems brought by different light conditions. And please note that if the color of the lens turns to be too light in the sunlight, the lens is suitable for winter; otherwise, the lens is for summer.
