the defect of vision that arises due to gradual weakening of ciliary muscles in old age is presbyopia
-------------------
the person cannot see nearby as well as far objects clearly
it can be corrected by using bifocal lenses
this defect normally comes to old people as their muscles get weakened and wont function properly or wont contract or relax properly
