What are Photochromic Lenses and Why Should I Buy Them?
Protecting your eyes from ultraviolet damage caused by sun exposure is an important part of preventing eye problems later in life. Cumulative exposure to the sun’s UV rays is a common cause of cataracts and other eye diseases.
One of the most hassle-free and effective ways to protect your eyes from UV exposure is the photochromic eyeglass lens. Photochromic lenses often referred to as “transition” lenses, react to UV light rays causing them to darken, or tint, when exposed to the sun, providing 100 percent UV protection. When UV exposure subsides, the lenses will become clear again, allowing you to protect your eyes without purchasing and caring for a separate pair prescription sunglasses.
Because UV rays penetrate clouds, photochromic lenses will continue to transition between clear and tinted even in overcast conditions. However, vehicle windshields block most UV rays, so the lenses won’t fully transition inside a vehicle while driving.
Photochromic lenses are available in nearly all lens materials and designs, but typically cost more than either standard clear prescription lenses or prescription sunglasses. But the added convenience of maintaining just a single pair of glasses can be worth the cost.
