The importance of blocking bluelight

Blue light contributes to digital eye strain andcauses oxidative stress in the retina.

What are the advantages of photochromic lenses?

- Advantages:
1. They protect your eyes against the harmful UV rays of the sun.
2. They provide the convenience of having clear lenses indoors while having a tinted lens outdoor without the need of having multiple pairs.
3. They provide varying level of tinting based on the lighting conditions of the current situation.
4. They can be placed in almost any frame on the market.

Disadvantages:
1. They take time to lighten and darken. Darkening takes about a minute while lightening can take 15 minutes or more.
2. The darkening characteristics vary on temperature. The warmer the temperature the less the lenses darken. The colder the temperature the darker the lenses get.
3. Most don't work effectively in a car due to the windshield and windows blocking most of the UV rays needed to darken the lenses.
