Which of the following would be used in eye glasses to correct nearsightedness?

57% Answer Correctly

concave lens

convex mirror

concave mirror

convex lens
Solution

Unlike curved mirrors that operate on the principle of reflection, lenses utilize refraction. A convex lens is thicker in the middle than on the edges and converges light while a concave lens is thicker on the edges than in the middle and diffuses light. A common use for curved lenses is in eye glasses where a convex lens is used to correct farsightedness and a concave lens is used to correct nearsightedness.
