Myopia Causes

Myopia is better known as Nearsightedness or Shortsightedness. Myopia is a vision disorder wherein the person can clearly see those objects which are near to him/her. But the objects at a distance appear to be blurred. Myopia is a common eye disorder which is majorly seen in the inhabitants of Asian countries. Myopia initially appears in the eyes of school going children. As they are growing day by day, so also it tends to increase till they reach the age of 20 years.
