The vision defect 'nearsightedness' is known as.

Explanation

The defect of short-sightedness is called Myopia (Myopia). A person suffering from this defect can see nearby objects easily, but cannot see distant objects. This problem occurs due to a decrease in the focal length of the eye lens, an increase in the curvature of the lens, and an increase in the power of the lens. To correct it, a concave lens (Concave Lens) of suitable focal length is used.
