What is the other name of old age hypermetropia?


Presbyopia is the other name of old-age hypermetropia.

Explanation

Presbyopia, is a defect of vision in which an old person can't see the nearby object clearly (appears blurred), due to the loss of power of accommodation of the eye. The near point of the presbyopic eye gradually recedes and becomes much more than 25 cm away.  It is also called a special kind of hypermetropia or old age hypermetropia.

This defect occurs in old age due to the weakening of the ciliary muscle and the eye-lens becoming inflexible (or rigid). Thus, the eye loses its power of accommodation. It is corrected in the same way as hypermetropia by using spectacles containing convex lenses.
