Final answer:

A concave lens in glasses for nearsightedness helps by diverging light rays to compensate for the eye's overconvergence, enabling clear vision of distant objects.


Explanation:

Nearsightedness, also known as myopia, is corrected using a concave lens in glasses. The concave lens helps diverge light rays before they enter the eye, compensating for the overconvergence of light by the nearsighted eye. This allows the nearsighted person to see distant objects clearly by creating an image closer to the eye than the physical object.
