Nearsightednessby David A. Wallace MD
 Nearsighted View: Clear Close, Blurry Far © 2002 Robert Meyers Studio. | Nearsightedness (myopia) is the most common optical condition in adults worldwide, affecting about 35% of the population. In the nearsighted eye, light from distant objects focuses in front of the retina, not on it; so a blurry image is perceived. Concave lenses are used to correct this condition.Correcting Nearsightedness by laser treatment involves precisely sculpting the desired correction into the cornea. Glasses and contacs work by adding a concave lens to the eye, whereas laser treatment works by evaporating or subtracting a convex lens shape from the cornea.
