Studies have shown that people inherit a tendency to develop nearsightedness. But intense close-up visual activity may contribute to the development of the condition. Some babies develop nearsightedness by age 1, but the problem corrects itself as the eyes grow. Research indicates these individuals usually develop the defect again during or after adolescence. Nearsighted people can wear concave glasses or contact lenses to clear up their distance vision.
Concave lenses are thinner in the middle than at the edges.
They bend light rays outward so that the rays meet on the retina. A surgical procedure called radial keratotomy can correct nearsightedness. Laser surgery also can reshape the cornea and correct nearsightedness. However, the long-term results of these surgical procedures are unknown. How to cite this article.
