Description

  • Photochromic lenses have millions of molecules of substances such as silver chloride or silver halide embedded in them. When exposed to UV rays, as in direct sunlight, the molecules undergo a chemical process that causes them to change shape.
  • The new molecular structure absorbs portions of the visible light, causing the lenses to darken, and to improve vision while ensuring protection from hazardous optical radiation.

  • The darkening of photochromic lenses was reversible, i.e., the lenses became original shape again once the ambient light was lowered.
  • Because they react to UV light and not to visible light, there are circumstances under which the darkening will not occur.
  • First example, is in your car. Because the windshield blocks out most UV light, photochromic lenses will not darken.
  • Second,is indoors test with ordinary lighting(Because the lighting used in daily lighting does not contain ultraviolet light),photochromic lenses will not darken. So the ways to activate photochromism: Exposed to UV rays, as in direct sunlight OR Use ultraviolet light lamp (not ordinary lighting lamp).This is the way to activate the photochromic function of the product.
