If the whiteboard at school looks blurry or you cannot clearly read street signs far away, you may have myopia, also called nearsightedness. Myopia develops when the eyeball becomes too long or the cornea curves too much, causing light to focus incorrectly on the retina. As a result, nearby objects look clear, but distant objects appear fuzzy. The condition is becoming more common among children and teenagers, especially in today’s digital world.
Common signs of myopia include squinting, headaches after studying, and tired eyes after spending too much time on screens. Eye doctors recommend regular eye exams because early treatment can help prevent vision problems from worsening. Glasses and contact lenses are the most common treatments. Some people also use Ortho-K lenses, which are worn overnight to gently reshape the cornea during sleep.
Experts suggest spending at least two hours outdoors each day for eye health. Doctors also suggest following the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds to reduce eye strain.
