How do self-tinting glasses work?

Answer 1

Transition lenses that are created using Chromea7 technology are available in grey, brown, and green.

If you wear prescription eyeglasses and choose not to wear any type of sunglasses because you do not want to swap your eyeglasses for sunglasses every time you walk outside, we suggest that you wear transition safety glasses.

We think you will find many advantages in the polycarbonate material because it is the safest material that you will find in glasses. However, we understand that you may be hesitant to purchase transition lenses in safety glasses.

The technology that is being used in transition lenses continues to improve. The transition lenses are now being created using lens material that is so lightweight that they can easily adjust to any lighting condition faster than you can walk outside, walk through the parking lot, and get into your car. The transition lenses can become dark or light to the smallest change in whatever environment you are in. You will not have to worry about your lenses being too light or too dark for the type of environment you are in.

Answer 2

Self-tinting glasses, also known as photochromic lenses, contain photochromic molecules that respond to UV light. When exposed to UV radiation, the molecules in the lenses undergo a chemical process that causes them to darken, providing protection from sunlight. Once the UV light is removed, the lenses gradually return to their clear state.

Answer 3

they reflect the sunlight off the sun and then the solar radiation and it causes a chemical reaction that tints the glasses
