Blue Light Damage: How Screens Affect Your Eyes
Share
8+ hours of screens daily is the new normal. The science on macular fatigue, dryness, and what actually helps.
High-energy blue light (415-455nm) penetrates deeper into the eye than UV, reaching the retina directly. Long exposure is linked to oxidative stress in the macula and accelerated digital eye strain.
Symptoms creep in slowly: dry eyes by 3pm, blurred vision after work, headaches behind the brow. The cause is almost always cumulative — not one bad day.
Lutein, zeaxanthin and astaxanthin act as the eye's natural sunglasses, filtering blue light at the macula. Pair with the 20-20-20 rule (every 20 mins, look 20 feet away for 20 seconds) for measurable relief in 8-12 weeks.
