For myopia, also known as nearsightedness, the vision is clear for nearby objects while distant objects appear blurred. A concave lens is specially designed to correct this refractive error. When a concave lens is placed in front of a myopic eye, it diverges the light rays before they reach the eye, effectively allowing the image to be focused on the retina rather than in front of it. This correction enables individuals with myopia to see distant objects more clearly.

The other types of lenses serve different purposes; for instance, a convex lens is used to correct hyperopia (farsightedness), a cylindrical lens is used for astigmatism, and multifocal lenses are designed for presbyopia and other conditions needing correction at various distances. Therefore, the concave lens is the appropriate choice for managing myopia, providing the necessary correction to achieve clear distance vision.
