Photochromic Reading Glasses for Men & Women - Light Adjusting Transition Lenses - Perfect for Indoor/Outdoor Reading, Driving & Computer Use

The Transformer Photochromic Reading Glasses are a unisex trasition reader for men and women. Here are some of the biggest pros to getting a pair of transitional lenses: Cost effective – Photochromic or transitional lenses can be quite cost effective. With transitional lenses, you will not have to buy two pairs of glasses: sunglasses and clear lens glasses. You get the best of both worlds, rolled into one simple solution. Convenient – Transitional lenses are very convenient because they save you from having to carry around two pairs of eyeglasses and having to switch between them to meet different needs. With transitional lenses, you can wear sunglasses while driving and still be able to read important street signs. Limits risk of losing glasses – Carrying around two pairs of glasses means that you’re much more likely to lose or misplace one of them. Having only one pair makes it easier on you. Protects your eyes – Transitional lenses do more than function as sunglasses. They filter out a good deal of the harmful UV rays emitted from the sun, leading to healthier and happier eyes.

Photochromic glasses are clear when indoors or at night and automatically darken to a sunglasses tint when exposed to UV sunlight (may not change obviously under weak UV lights). Lenses will begin to clear as soon as they are away from UV sunlight, and will be noticeably lighter and mostly clear within a few minutes. They absorb UV radiation that can otherwise damage your eyes. They are an excellent solution for people who hate constantly switching between their reading glasses and their shades.

A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation. In the absence of activating light, the lenses return to their clear state. They are principally used in eyeglasses that are dark in bright sunlight, but clear in low ambient light conditions. They darken significantly within about a minute of exposure to bright light and take somewhat longer to clear.

Transition glasses have lenses that change tint depending on the weather or surroundings. The benefit of transition lenses is that in dull, overcast weather, or darker surroundings (like cycling through the woods or early / late in the day) they will lighten. But in bright, sunny conditions they will turn to tinted sunglasses. Photochromic lenses do a great job of stopping the dazzling effects of sunlight when you are driving, running, fishing, biking, golfing, and all outdoor activities.
