Distant objects appear blurry, but near objects appear clear.
Nearsightedness is very common in the U.S., affecting about 30 percent of the population. There is some evidence that nearsightedness is caused by too much near work. Nearsightedness is usually first found in school age children, especially while children are growing. If you or your child have experienced these signs, a comprehensive eye exam by your eye doctor can test for nearsightedness. Eyeglasses or contact lenses can correct nearsightedness by altering the way light falls on the back of the eye.
