The light transitional eyeglasses with photochromic lenses include silver halide molecules that momentarily change color when bared to ultraviolet light. It composes a cover that works on the molecular level. The particles embed in this coating are transparent when they are expose to most forms of light, but change their form when shown to the sun’s ultraviolet (UV) rays. In the presence of UV light, these particles change shape and start to absorb more of the light spectrum. This happens in a progressive darkening effect.
Since the molecules are layered, they’re not flashed to UV light all at once; in low levels of UV light, some of the particles maintain their original shape. So, in full sunlight, all the molecules turn, and the lenses reach their darkest tone. This is how the level of shade alters with the amount of light that is present.
