OCULOMOTOR MACROPSIA

A term used to denote amagnification(i.e. an apparent increase in size) of a visually perceived object or stimulus that is attributed primarily to accommodation and divergence of the eyes. It is conceptualized as a * physiological illusion that occurs when one views objects farther away than a metre, while the eyes are in their resting focus position, i.e. focused at a distance of about 1 m. Oculomotor macropsia may play a role in the mediation of the *Moon illusion. The term is used in opposition to *oculomotor micropsia.
