A person can be considered as myopic when he can see nearby objects clearly but cannot see distant objects distinctly. This defect of eye is called myopia.
When the person cannot see nearby objects clearly but able to see distant objects clearly, the person can be treated as hypermetropic. The eye defect is called hypermetropia.
Correction of Hypermetropia: The convex lens forms a virtual image of the object (lying at normal near point N) at the near point 'N' of defective eye. It helps the eye to form the image on the retina.
