What is Blue Light

Also know as "HEV" High Energy Visible Light.  The largest source of blue light is sunlight.  In addition, there are many other sources:

Flourescent light

CFL (compact flourescent light) blulbs

LED light

Flat screen LED Televisions

Computer monitors, smart phones, and tablet screens

Blue light exposure you receive from screens is small compared to the amount of exposure from the sun.  And yet, there is concern over the long-term effects of screen exposure because of the close proximity of the screens and the length of time spent looking at them.

According to a recent NEI-funded study, children's eyes absorb more blue light than adults from digital device screens.                 -Preventblindness.org

How to Reduce Exposure

Technological advances in the optical industry allow us to reduce exposure to blue light with a HEV filter added to anti-reflective coatings.  This combination helps to reduce blue light as well as UV rays and artificial glare all in one coating!
