Chronic Problems Linked to Overexposure to High Energy Blue Light

  • Macular Degeneration - Harmful Blue Light penetrates the macular pigment and harms the retina
  • Cataracts - UV light is absorbed by the lens, causing cloudiness
  • Pterygium - UV light causes a tissue growth to form on the cornea

Blue Light Can Disrupt Sleep

Our bodies are hardwired to respond to blue light:

  • Heightens alertness
  • Improves mood and sense of well being
  • Boosts reaction times

Exposure to blue light within an hour of going to sleep can interrupt your sleep cycle by making you more alert More than 80% of Americans look at screens within an hour of going to bed

Flickers Create Harmful Glares

  • Higher energy light tends to flicker more easily, causing glares
  • Glares cause your eyes to fight harder to see
  • Suspected cause of many digital eye strain symptoms

  • 18 months - 2 years: monitored time with quality programming
  • 2 years - 5 years: 1 hour max. of quality programming
  • 5 years+: spend time on screens according to parental guidance

Helpful Habits

  • Use the 20-20-20 rule: Look at something 20 feet away for 20 seconds every 20 minutes. Allows eyes to relax
