Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Differentiate between myopia and hypermetropia.

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Myopia is also called nearsightedness as one can clearly see the objects close to them but objects which lie far away look blurred. It can be corrected via a concave lens.
Hypermetropia is also called farsightedness. One cannot clearly see the objects close to them but objects which lie far away are clearly visible. It can be corrected via a convex lens.
