Question

Write a short note on hypermetropia and its correction.

Hint:

Convex lenses help converge light rays to focus the image on the retina for hypermetropia correction.

Answer 1

Hypermetropia, also known as farsightedness, is a condition where distant objects are seen clearly, but nearby objects appear blurred. This occurs when the eyeball is too short or the lens has too little curvature. The focal point of the eye is beyond the retina. To correct hypermetropia, convex lenses are used, which bring the focal point closer to the retina, allowing clear vision for nearby objects.
