General EYE ADVICE

Refractive State

By about sixty years of age, the focusing power in the eye reduces close to its lowest level. After this age, there is a reduction in the frequency of changing of the presbyopic lens prescription, provided there are no other causative factors such as cataract etc. Patients are often surprised that they can see with the same pair of glasses almost ten years later (i.e. at seventy years of age). Of course, many people do require a change in prescription for other reasons, particularly cataractous changes.

A common complaint relating to spectacles is the difficulty that one experiences in adjusting to new spectacles due to a change in the astigmatism (type of vision defect) of the eyes. A detailed discussion of the subject of astigmatism can be found in Part II (A). The recommendations under Part I (D) relating to presbyopia are also relevant.
