Presbyopia is generally focused power of eye lens decrease with age .The muscle near the lense lose ability to change focal length of lens. These people suffer from both farsightedness and nearsightedness

It can be corrected by using bifocal lens in which concave lens is useful for distinct vision and convex lens is useful for near vision
