A study of 4,500 U.S. children over 20 years has identified a single test that can predict which kids will become nearsighted by the eighth grade: a measure of their current refractive error. The refractive error, or eyeglasses prescription, results from mismatches in the size and optical power of the eye that lead to blurry vision.
