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.

BLUE LIGHT SPECTRUM. Blue-Violet Light, or Harmful Blue Light, is believed to be the most harmful to the retina. Blue-Turquoise Light has positive effects on the body, such as regulating the sleep/wake cycle.
