BENEFICIAL VS. HARMFUL BLUE LIGHT
Blue light is everywhere. While it’s emitted mainly by the sun, it’s also emitted by artificial lights and digital devices.
Harmful Blue Light ranges from 400-455 nm with the greatest toxicity between 415-455 nm.
Beneficial blue-turquoise light ranges from 465 – 495 nm. Blue-turquoise light stimulates the eye’s pupillary reflex and parts of the brain where melatonin is produced.
Patients need a solution that protects their eyes from harmful blue-violet light while letting beneficial blue-turquoise light pass through.
