With summer almost here, many of us are looking forward to spending a lot of time outdoors.
Before we head out, though, we need to make sure we’re protecting ourselves from the sun’s UV rays, both with sunscreen for our skin and with sunglasses for our eyes.
But are you still worrying about switching between prescription eyeglasses and sunglasses?
Here is a cool and convenient way to turn your glasses into sunglasses.

How do Photochromic lenses work?

Photochromic lenses are coated with special molecules, such as silver chloride, that change shape and absorb light when exposed to UV rays. It is this reaction that causes them to darken in sunlight. When taken away from UV light, the process reverses, causing the lenses to gradually become lighter. The lenses typically take around 15 minutes to fully darken, although some change will be seen within the first minute.

These lenses are designed to quickly adjust from clear to dark.
This allows eyeglasses and sunglasses to be one.
