Question

Quizplus · Accepted Answer

Nearsightedness is caused by a longer eyeball, which causes light to focus in front of the retina instead of directly on it. Diverging lenses help to spread out the incoming light, which then focuses correctly on the retina. Converging lenses would only worsen the problem by further focusing the light in front of the retina. Achromatic lenses are used to minimize chromatic aberration (color distortion), and cylindrical lenses are used to correct astigmatism (irregular curvature of the cornea or lens). Spherical lenses are used for various vision problems, but they would not be the best choice for correcting nearsightedness specifically.
