Accommodative excess

Accommodative Excess

Accommodative excess (pronunciation: uh-kom-uh-dey-tiv ek-ses) is a condition in optometry where the eyes over-focus or accommodate more than necessary to maintain clear vision at a given distance. This over-accommodation often leads to symptoms such as headaches, blurred vision, and eye strain.

Etymology

The term "accommodative" is derived from the Latin word "accommodatus" which means "adapted". "Excess" comes from the Latin word "excessus" meaning "going beyond". In the context of optometry, it refers to the eyes' over-adaptation or over-focusing beyond what is necessary for clear vision.
