Question

A person got his eyes tested. The optician's prescription for the spectacles reads:
Left eye: − 3.00 D
Right eye: − 3.50 D
The person is having a defect of  vision called:
(a) presbyopia
(b) myopia
(c) astigmatism
(d) hypermetropia

myopia

The optician has prescribed concave lenses for the person's spectacles, as a concave lens decreases the converging power of the eye lens. This shows that the person is suffering from short-sightedness, or myopia.
