What is blue light?

Blue light’s high-energy waves are similar to UV rays but visible to the human eye.

Whether it’s sunny or cloudy, you’ll find high concentrations of blue light outdoors from the sun’s rays. Indoors, sources of blue light include digital devices (TVs, tablets, phones and computers) and artificial lighting—especially fluorescent and LED lights.

Why is blue light harmful?

Our eyes offer a natural filter for most light, but they don’t provide sufficient protection against blue light rays.

This leaves us exposed to its harmful effects, and prolonged exposure to blue light may cause retinal damage or lead to vision loss, just as prolonged UV exposure can harm healthy skin.


Research from medical professionals indicates blue light exposure may cause:

  • Macular Degeneration and Cataracts
  • Headaches, Eye Strain and Discomfort
  • Sleep Disorders
  • Diminished Concentration
  • Behavioral and Anxiety Issues
  • Computer Vision Syndrome
  • Health Problems such as Cancer, Diabetes and Obesity

Who’s most at risk?

Children and seniors are most at risk.

Because children’s retinas aren’t fully formed, they are highly susceptible to infiltration of harmful rays.

As seniors age, the protective layers on their retinas diminish, leaving them even more exposed to blue light rays. This exposure can cause aged-related macular degeneration and cataracts.
