Excessive screen time causes digital eye strain, accelerates myopia, and reduces outdoor protective light exposure in Lagos children. SpecSMART Eye Clinic Ikeja offers comprehensive pediatric exams and myopia management to protect developing vision.
3 Critical Screen Time Impacts
1. Digital Eye Strain (70% of Children)
-
Headaches after homework/gaming
-
"Sandy" eyes, frequent rubbing
-
Blurred vision (improves with blinking)
-
Blue light damages developing retina
2. Myopia Epidemic Acceleration
2+ hours screen time daily =
3x higher myopia risk
Eye physically elongates from constant "near work"
3. Outdoor Light Deficit
Natural sunlight releases retinal dopamine = stops eye elongation
