Question

If a person cannot see an object at distance of 30 cm, then which disease the person if suffering from myopia or hypermetropia and why??

Answer 1

This condition is referred to as hypermetropia. In this condition an individual can see distant objects clearly but not objects at close distant, for instance at 30 cm distant. The image is formed beyond the retina.
Myopia is a condition where an individual can see objects at a close distant clearly but not those far off. Here the image is formed in front of the retina and not on it.
