Say goodbye to switching glasses: Are you looking for a new pair of glasses with self-tinting lenses that will give you 100% protection from the sun and harmful UV rays? Did you know that lenses that darken in the sun are now popular modern miracles that offer optimum vision? We’ll tell you why you should buy them and what you need to look out for.
What are Transitions lenses?
They are also known as Photochromic lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Other terms sometimes used for photochromic lenses include "light-adaptive lenses" and "variable tint lenses."
The molecules responsible for causing photochromic lenses to darken are activated by the sun's ultraviolet radiation. Because UV rays penetrate clouds, photochromic lenses will darken on overcast days as well as sunny days.
Photochromic lenses typically will not darken inside a vehicle because the windshield glass blocks most UV rays. Recent advancements in technology allow some photochromic lenses to activate with both UV and visible light, providing some darkening behind the windshield.
