Question

when we wear spects if the letter size is small when observed what does it mean?

Answer 1

it means that the person is suffering from hypermetrophia, if he can't see near objects and suffer from myopia..if he can't see distant objects...

Answer 2

Hypometropia is a defect in which we cannot see near objects clearly because the image of the object falls behind the retina.This defect can be corrected by using convex lens of appropriate focal length.
