Question

Name the defect of vision the person is suffering from.

Hint:

For correcting hypermetropia, convex lenses are used, and their power is calculated as \( P = \frac{1}{f} \). A positive power indicates the use of convex lenses.

Answer 1

The person is suffering from hypermetropia (farsightedness), which is a defect of vision where distant objects are seen more clearly than near objects. This defect occurs when the eye is too short or the cornea has too little curvature, causing light to focus behind the retina. Convex lenses are used to correct this defect by converging light before it enters the eye.
