1) An eye that suffers from myopia as well as from hypermetropia is said to suffer from presbyopia. A person with this defect cannot see objects distinctly placed at any distance from him. To correct this defect, a person is prescribed bifocal lens that has both types of lenses convex and concave.

This means that light is focused too far back in the eye, causing things which are close up to appear blurred. Hyperopia can be corrected with a convex lens.
