Question

What is hypermetropia ? Draw the diagram and show how is corrected

Answer 1

HEY MATE!!!!_____________________

Hypermetropia, sometimes called hyperopia, is the term used to define being longsighted.

If you are hypermetropic, the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.

HOPE THIS HELP YOU..

Answer 2

A person suffering from hypermetropia can see distinct objects clearly but faces difficulty in seeing nearby objects clearly. It happens because the eye lens focuses the incoming divergent rays beyond the retina. This defect of vision is corrected by using a convex lens. A convex lens of suitable power converges the incoming light in such a way that the image is formed on the retina, as shown in the following figure.
