There are two types of mirror concave mirror and convex mirror.
There are three types of eye defects namely myopia, hypermetropia, and presbyopia. In myopia you can't see far objects, in hypermetropia you can't see closer objects, and in presbyopia you can't see both far as well as close. For myopia you need convex lenses and for hypermetropia you need concave lenses where as you need special operations in case of presbyopia .
