A photochromic lens that controls light by changing its color based on the amount of ultraviolet (UV) light
Material for eyeglass lenses
- Basic information
This lens material applies photochromic technology to change the light transmittance of the lens based on the amount of ultraviolet (UV) light in the environment. Outdoors and in strong sunlight, the glasses turn into sunglasses. Indoors, where UV does not reach easily, the lenses return to the clear state.
It blocks harmful UV light and controls glare for greater viewing comfort.
