Eye dominance (the technical term ocular dominance from the Latin oculus “eye” and dominus “lord”) refers to the fact that the retinal image of one eye of a living being is preferred over the retinal image of the other eye.
If the dominant eye and dominant hand are on different sides of the body, this is called cross dominance . Studies suggest that cross dominance has positive effects on aiming, for example, in clay pigeon shooting, golf, and archery.
Left-sided and alternating eye dominance, along with left-sidedness, are generally suspected of causing or contributing to learning difficulties.
When measuring eye movements using eye movement registration, the system must be calibrated specifically to the dominant eye in order to provide reliable results.
As with right- or left-handedness, the cause of ocular dominance is assumed to be the dominance of one brain hemisphere. During the development of vision, so-called ocular dominance columns (ODCs) develop in the visual cortex, the brain area where visual impressions are processed.
These columnar clusters of neurons, which can be identified as a stripe-like pattern in the exposed brain, are connected to either an axon of the right or left eye and extend across several neuronal layers.
Normally, the ocular dominance columns are distributed approximately equally between both eyes; however, if one eye is dysfunctional during development, only the columns of the other eye grow and occupy the visual cortex. The development of the ocular dominance columns is probably responsible for ocular dominance, binocular vision and depth perception.
