Photochromic reading glasses transition lenses have the ability to self-adjust color based on light intensity. Indoors or at night, the lenses stay clear. When the lenses are exposed to ultraviolet sunlight, these clear vision multifocal eyewear lenses automatically darken to the tint of sunglasses, adjusting the strength of the light. Once out of ultraviolet sunlight, the lenses gradually become clear again. A pair of multifocal photochromic sunglasses for men and women will meet all needs.
