What are photochromic lenses?

Photochromic glasses are "smart" lenses that turn dark when they are outside in UV light and clear when they are inside. It's like wearing prescription glasses and sunglasses at the same time, so you don't have to carry around extra pairs of glasses when you go hiking, commuting, or running tasks.

How do photochromic lenses work?

Photochromic glasses are made up of molecules that change colour when exposed to light, such as silver halide. These are the simple facts that make it work: Outdoors: UV light makes these molecules rearrange, which darkens the lenses (just like quick-action shades). Indoors: Inside, where there is no UV light, the molecules go back to how they were before, which makes the glasses clear. The ZEELOOL glasses are clear even on cloudy days and change colour in seconds.

Do photochromic lenses work in the car?

Since most windscreens stop UV rays, photochromic lenses don't get very dark while you're driving. To make driving more comfortable, ZEELOOL makes polarised shades that cut down on glare.
