Answer:
Presbyopia is when your eyes gradually lose the ability to see things clearly up close. It is a normal part of aging. In fact, the term “presbyopia” comes from a Greek word which means “old eye.” You may start to notice presbyopia shortly after age 40.

✍️Presbyopia is the defect of vision. During this, people find it difficult to see the nearby objects clearly and comfortably without their spectacles, Because the near point of the lens shifts farther from the eye.Hence old people cannot see nearby objects clearly.
✍️This defect can be corrected by using a convex type of lens of suitable focal length.
