   Presbyopia
   Pres`by·o'pi·a [ New Latin , from Greek ... old, noun , an old man + ..., ..., the eye.] (Medicine) A defect of vision consequent upon advancing age. It is due to rigidity of the crystalline lens, which produces difficulty of accommodation and recession of the near point of vision, so that objects very near the eyes can not be seen distinctly without the use of convex glasses. Called also presbytia .

    Presbyopia
    `Presbyopia` describes the condition where the eye exhibits a progressively diminished ability to focus on near objects with age. The exact mechanisms of presbyopia are not known with certainty, however, the research evidence most strongly supports a loss of elasticity of the crystalline lens, although changes in the lens's curvature from continual growth and loss of power of the ciliary muscles (the muscles that bend and straighten the lens) hav...

    presbyopia
    (pres″be-o´pe-ә) lessening of accommodation of the lens of the eye, a process that happens normally with aging and usually results in farsightedness (hyperopia). It is caused by a loss of elasticity in the crystalline lens, which focuses images on the retina with the aid of muscles that stretch it to make it less ...

    presbyopia
    A loss of accommodation that normally develops in human eyes over the age of 45 to 50 years. Vision of distant objects remains unchanged but as the eye lens gets older it loses some of its ability to change curvature to focus on near objects. Presbyopia is easily corrected by spectacles or contact l...
