Photochromic lenses are simply light-adaptive lenses, but they do massive roles in protecting your eyes. They say that life should be lived to the full extent, but we say life should be enjoyed with utmost care especially when it comes to the eyes.
According to the World Health Organization, of the 42 million people affected by severe loss of vision, 17 million cases are caused by an eye condition called cataract. The Philippines has 400,000 loss of vision due to long-term exposure to ultraviolet rays. That’s more than enough cases to teach us a lesson. And since cataract is only one of the five major conditions resulting from exposure to UV rays through the years, utmost care should be applied while time still permits. What should you do in order to enjoy the outdoor activities without having to suffer from one of these conditions through time?
Hiking, golfing, biking, and gardening have one common denominator, and you surely love to do one (if not all) of these that are usually performed under the heat of the sun. These outdoor activities and prolonged usage of technological devices both pose a damage on the eyes if they do not receive extra care from you. Photochromic lenses have different types; they have molecules that activate when triggered by harsh outdoor light such as that coming from the sun.
Say, you are outdoors enjoying any of the abovementioned activities. You may expect that the clear lenses will have turned into dark-colored lenses, completely capable of protecting the eyes from UVA and UVB lights. How cool is that! It’s like having eyeglasses and sunglasses rolled into one. However, it must be noted that the degree of discoloration varies depending on the degree of light the photochromic lenses receive.
You must be aware by now that skin is not the only organ that deserves UV protection; the eyes also do! Photochromic lenses can be more powerful by adding anti-reflective coating so that it’s easier for you to drive at night or even under bright conditions.
