Name the defect of vision which can be corrected by a diverging lens. Show clearly by a ray diagram how the lens corrects the defects.

Concave lens is used for correcting myopia. Following is the ray diagram of the correction of myopia:

(a) The image formation for a myopic eye will happen in the front of the retina.

(b) F is the far point of a myopic eye which is less than infinity.

(c) The concave lens is placed in the front of the eye which forms a virtual image of an object placed at a distance.
