Photochromic lenses are eyeglass 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."

1) What is the photochromic lens?

Anti UV Photochromic Lenses Hard Coating 1.56 Refractive Index

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. Ask your optician for details.

2) How is the phtotochromic lens?

First let's cut through the jargon. The word "photochromic" comes from two Greek words: "photos" meaning light and "chroma" meaning color. So photochromic simply means something that changes color in response to light. In those days, photochromic glassworked a bit like pieces of old-fashioned, photochromic film.

3) Why do we wear the photochormic glass?

Wearing eyeglasses can often be a pain. If it's raining, you're wiping water off the lenses, if it's humid, the lenses mist up; and if it's sunny, you don't know whether to wear your normal glasses or your shades and you may have to keeping switching between the two! Many people who wear eyeglasses have found a solution to the last of these problems by changing over to photochromic lenses
