Answer 1

Step-by-step explanation:

This defect arises due to either of the following two reasons: (i) The eyeball becomes too small along its axis so that the distance between the eyelens and the retina is reduced. (ii) The focal length of the eyelens becomes too large resulting in the low converging power of the eyelens.$<marquee><h1><fontcolor=green>$ Hope it helps.......

Answer 2

Step-by-step explanation:

Hypermetropia or long sightedness : It is the defect of human eye in which a person can see clearly objects at large distances from it. but cannot see nearby objects clearly.

Correction : It is corrected by using spectacles having convex lens, which converges and shifts the image to retina from beyond.
