Vedclass · Answer

(C) $Presbyopia$ is a vision defect that occurs due to the gradual weakening of ciliary muscles and diminishing flexibility of the eye lens with aging. This condition makes it difficult for a person to see nearby objects clearly. To correct this defect,a $Bifocal$ lens is used,which consists of both concave and convex lenses. The upper part of the lens is concave (for distant vision) and the lower part is convex (for near vision).

The eye defect known as $Presbyopia$ is corrected by using a $........$ lens.
