  1. A lens is usually embedded with tiny silver halide and chloride molecules that darken when exposed to UV rays or sunlight.
  2. Due to a chemical process, the lens darkens when it is exposed to sunlight or UV light.
  3. As soon as the molecules are exposed to light, they move, change shape and absorb the light.
