The real problem
Blue light doesn't damage your retina day to day. The real issue is digital eye strain: dry eyes, blurred vision, headaches after hours on screens.
What helps
- 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds.
- Blue-light filter lenses: available at Opti-W, they reduce evening strain. See our specialty lenses.
- Night mode on your devices.
- Distance: 20-28 inches from the screen, slightly below eye level.
Sleep
Blue light at night disrupts melatonin. Avoid screens 1 h before bed, or wear filtering lenses.
Get your eyes checked
If strain persists, an exam can rule out a hidden prescription. Book an exam at your Opti-W clinic.
