Why do I need blue-light blocking glasses?

Last Updated: Nov 22, 2017 12:26PM EST

There are two types of blue light, Blue-Turquoise, and Blue-Violet. Blue-Turquoise light is good for the eyes. It aids in visual acuity, color perception, aids the pupil constriction reflex and helps sync our biological clocks.

Blue-Violet light can be harmful to the eyes. It is the closest on the spectrum to non-visible and harmful light. It can contribute to macular degeneration, retinal cell damage, early onset cataracts and it can also increase visual fatigue.

Blue-blocking glasses will filter the harmful Blue-Violet light while allowing the helpful Blue-Turquoise light pass through. The use of blue-blocking lenses will assist in combating eye strain, headaches, and fatigue from using Blue-Violet emitting devices and computers.
