    Photochromic lenses are also known as “photosensitive lenses”. According to the principle of reversible reaction of light color alternation, the lens can quickly darken under light and ultraviolet radiation, block strong light and absorb ultraviolet light, and show neutral absorption to visible light. Back to dark, can quickly restore colorless transparent state, ensure the lens transmittance. So the color changing lens is suitable for indoor and outdoor use at the same time, to prevent sunlight, ultraviolet light, glare on the eye damage.

    Photochromic progressive lens is the progressive lens designed with “photochromic molecules” that adapt to varying lighting conditions throughout the day, whether indoors or outdoors. A jump in the amount of light or UV rays activates the lens to turn darker, while little lighting causes the lens to revert back to its clear state.

    Index 1.60 lenses are thinner than Index 1.499,1.56 lenses. Compared to Index 1.67 and 1.74, 1.60 lenses have higher abbe value and more tintability.blue cut lens effectively blocks 100% UV and 40% of the blue light, reduces the incidence of retinopathy and provides improved visual performance and eye protection, allowing wearers to enjoy the added benefit of clearer and shaper vision, without altering or distorting color percepyion.An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun’s harmful UVA and UVB rays.
