You may get a headache when you try to focus on something near your face. If you're farsighted, things look fuzzy as you get closer to them. It could be because your eyeball is too short or the clear covering on your eye, called the cornea, is too flat. You might be born with it, but it starts to happen to most folks after age 40. Your doctor can help with eyeglasses, contact lenses, or surgery that corrects the shape of your cornea.
