Question

A person uses lenses of power -0.5 D in his spectacles for the correction of his vision. (a) Name the defect of vision the person is suffering from.

Hint:

Myopia (nearsightedness) is corrected using concave lenses, which diverge light rays to focus images on the retina.

Answer 1

The person is suffering from myopia (nearsightedness), which is corrected using concave lenses. In myopia, distant objects appear blurred, and the person requires a concave lens to diverge the light rays before they enter the eye, allowing the eye to focus correctly.
