Question

A person with myopic eye cannot see objects beyond 2m distinctly ,what should be the type of the corrective lens used to restore proper vision?

Answer 1

con cave lens can be used to restore proper vision

Answer 2

The lenses should be a concave lenses

far point(v)=2m

Object distance(u)=infinate

1/f=1/v-1/u

1/f=1/(-2)-1/infinite

f=-2

Power(D)=1/f

D=-0.5D

So,the lenses will be a convex lenses of power -0.5diopter
