Question

a convex lens of suitable power is used in to the correct hypermetropia
give reason for the following question in short
​

Answer 1

Answer:

Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye's lens and retina is too short, as a result of which the focal point lies behind the retina. Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.

Explanation:

that's why convex lens are used in hypermetropia

hope it will be helpful for

Answer 2

Explanation:

Hypermetropia allows a person to see distant items clearly but not nearby objects clearly. The person's near point is further away than the regular near point (25 cm). This problem occurs when the focal length of the eye lens is either excessively long or the eyeball has gotten too tiny. A convex lens of adequate power can be used to fix this flaw. Converging lenses in eyeglasses offer the extra focussing strength needed to produce the image on the retina.
