What is Presbyopia ?
Presbyopia describes the condition whereby the amplitude of accommodation, or ability to focus on objects at near, decreases with increasing age. It is corrected by a different prescription for reading, which is additive to the normal spectacle correction used for distance vision. Some recent research indicates that presbyopia may be caused by structural changes in the tendons and elastic fibres of the posterior ciliary body. The age related increase in fibrillar material could cause decreased compliance of the posterior insertion of the ciliary muscle.
