Discover the World of Farsightedness

Farsightedness, also known as hypermetropia, is an eye defect in which a person is unable to see nearby objects clearly but can see far away objects clearly. It is caused due to the eyeball being shorter than normal or the cornea having less curvature than required.

Nearsightedness, also known as myopia, is a defect of vision in which a person clearly sees nearby objects but is unable to see distant objects comfortably. It is caused due to the eyeball being longer than normal or the cornea having more curvature than required.

Farsightedness can be corrected by using a convex lens, which has the ability to converge incoming rays. The lens helps to focus the light properly onto the retina, allowing the person to see nearby objects clearly.

<p>Nearsightedness can be corrected by using a concave lens, which helps to diverge incoming rays. The lens helps to spread out the light before it enters the eye, allowing the person to see distant objects more comfortably.</p> Signup and view all the answers
