Harmful Effects of HEV Light

What is Blue Light?

Blue Light is a high-energy visible light (HEV Light)
in the violet/blue band from
400-450nm in the visible spectrum

Visible light is part of the electromagnetic radiation that is technically visible to our eyes within 390 to 700nm wavelength.

Why is Excessive Blue-Light Harmful?

HEV Light below 430nm wavelength can cause serious photochemical-induced retinal injury and oxidative damage to our eyes, eg Macular Degeneration

Other minor harms can include:

  • Loss of Concentration
  • Sleep Disruption
  • Fatigue & Headaches
