1.56 Photogrey Blue Coating Photochromic Finished Lens

● The Ultimate Convenience: Glasses & Sunglasses in One
The "Photogrey" lens material is reactive to ultraviolet (UV) light. It automatically darkens when you go outside and clears up when you return indoors. Eliminates the need to carry a separate pair of prescription sunglasses, making it incredibly convenient for everyday activities.

● High Light Transmission for Great Vision​
Even though they can filter light, 1.56 photogrey blue coating lenses still let a lot of light through. When they’re clear indoors, the amount of light they let through can be as high as 96% to 98%. This makes sure enough light passes through the lens, so you can see your surroundings brightly and clearly. The blue coating on the lenses doesn’t just help with the photochromic function; it also reduces reflections. The anti-reflection feature of the blue coating works really well to cut down on glare from both natural and artificial light sources. Whether you’re reading, working on a computer, or driving, these lenses give you sharp vision without distortion, making contrasts better and letting you see colors accurately.
