Answer 1

Hey !!!

A student has difficulty in reading the black while sitting in the last row that means he have hypertrophic eye (far -sightedness ) in which a person can see the distant object but cannot see nearby object.

Thet type of defect of vision is corrected by using convex lens

➡ these type of defect of vision is arises either by 1 ) focal length of eye lens is too long

or, 2) the eyeball has become too short .

so by using convex lens of appropriate power , eye glasses with converging lenses provide the additional focusing power required for forming the image on the ratina .
