Question

why the convex lens is used in hypermetropia???​

Answer 1

Answer:

Convex lenses —

thickest in the middle,

over the optical center —

converge light,

shortening the focal length of light passing through them;

this is used to correct hypermetropia (farsightedness), which is typically caused by the eye being too short, so that light isn't focused in time before it hits the retina.

Answer 2

⭕convex lens is used in hypermetropia⭕

✔️because........

Since the light rays now appear to be coming from the eye's near point, the eye-lens can easily focus and form the image on retina. Convex lens is used for hypermetropia so as to increase the converging power of the eye-lens.
