When you're nearsighted, things in the distance look blurry. Doctors call it myopia. You're more likely to have it if:
- One or both of your parents have it
- You do lots of close-up reading
Nearsightedness can make it harder to drive, play sports, or see a blackboard or TV. Symptoms include blurred vision, squinting, and fatigue. To correct it, you can wear glasses, contacts, or get surgery in some cases.
