Designed for seamless day-to-night wear, these photochromic lenses automatically adapt to changing light conditions, offering both sun protection and crystal-clear vision indoors.

What Are Photo Gray Lenses?

Developed in the 1960s by Corning Incorporated, Photo Gray lenses are a type of photochromic glass lens that darkens in sunlight and lightens indoors or in low-light environments. These lenses contain silver halide crystals embedded in the glass; when exposed to ultraviolet (UV) light, the crystals undergo a chemical reaction that causes the lenses to darken. Once the UV exposure decreases, the lenses gradually return to their clear state. 

In bright sunlight- Lenses darken, providing UV protection and glare reduction similar to classic sunglasses.

Indoors or at night-Lenses return to a lighter tint, functioning as regular clear lenses.

Automatic adjustment-No need to switch between separate eyeglasses and sunglasses.

This advanced light-adaptive technology was a hallmark of premium eyewear in the 1960s-1980s and remains highly sought after by vintage eyewear collectors.
