Question

What is hypermetropia? List two causes for the development of this defect. Explain the method of correcting this defect with the
help of ray diagrams??? ​

Answer 1

Explanation:

Hypermetropia (long-sightedness) is a common eye condition where nearby objects appear blurred, but your vision is clearer when looking at things further away. If you feel your eyes are often tired and you have problems focusing on objects close to your eyes, you may have hypermetropia.

Answer 2

Answer:

this defect of the eye is hypermetropia. the eyeball becomes too short, so that light rays from the nearby object, say at point N, cannot be brought to focus on the retina to give a distinct image. Hypermetropia can be corrected by using convex lens of suitable focal length in spectacles.
