Question

Which type of lenses are used on miopic eye and hypermetropic eye.​

Answer 1

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

When a person suffers from Miopia he/she uses Concave lens

and

When a person suffers from Hypermetropia he/she uses Convex lens.

EXTRA INFORMATIONS :

CONCAVE LENS :

A concave lens is made up of a transparent medium bounded by two spherical surface such that it is thin at the middle and thick at the edge.

The image formed by a concave lens is always virtual and erect.

It is also diverging lens as it diverge the image.

CONVEX LENS :

A convex lens is made up of a transparent medium bounded by two spherical surface such that it is thick at the middle and thin at the edge. It is called converging lens as it converges the image.

The image formed is real or virtual.

Convex lens can also be called as bi-convex lens.

Answer 2

Myopia and hypermetropia are both easily corrected at Optical Masters using prescription glasses or contact lenses specifically designed to counteract the effect .

Myopia - concave

hypermetropia - convex
