Question

Which defect of vision can be corrected by using spectacles made from concave lenses??​

Answer 1

Myopia can be corrected by using spectacles made from concave lenses.

Answer 2

Explanation:

Myopia (short-sightedness or near-sightedness) is corrected by using spectacles containing concave lenses. The parallel rays of light coming from the distant object O (at infinity) are converged to form an image I in front of the retina due to which the eye cannot see the distant objects clearly.
