Also known as age-related farsightedness [5] (or as age-related long sight in the UK [6]), it affects many adults over the age of 40.

Anisometropia causes some people to have mild vision problems, or occasionally more serious symptoms like alternating vision or frequent squinting. However, since most people do not show any clear symptoms, the condition usually is found during a routine eye exam. [8] For early detection in preverbal children, photoscreening can be used.
