Information about ocular dominance

Ocular dominance, also known as eye dominance, is the tendency to prefer visual input from one eye over the other. It is somewhat analogous to the handedness of an individual, although the side of the dominant eye and the dominant hand do not always match. Approximately two-thirds of the population is right-eye dominant, while the remaining one-third is left-eye dominant.

Physiology[edit]

Ocular dominance is a result of the brain's processing of visual information. The visual cortex in the brain receives input from both eyes, but the input is not always equal. The dominant eye sends stronger signals to the visual cortex, which can influence depth perception and binocular vision.

Testing for Ocular Dominance[edit]

There are several methods to determine ocular dominance, including the Miles test and the Porta test. These tests involve focusing on a distant object through a small opening or with a finger, and then alternately closing each eye to see which eye maintains the object in view.

Significance in Vision Correction[edit]

Ocular dominance is an important consideration in vision correction procedures, such as LASIK surgery and the fitting of contact lenses. Understanding which eye is dominant can help optimize visual outcomes and ensure better visual acuity.

Ocular Dominance and Sports[edit]

In sports, ocular dominance can affect hand-eye coordination and performance. For example, in archery or shooting, knowing which eye is dominant can help athletes aim more accurately. Similarly, in baseball, a batter's ocular dominance can influence their ability to track the ball.

Research and Studies[edit]

Research into ocular dominance has explored its relationship with neurological development and plasticity. Studies have shown that ocular dominance can be influenced by visual deprivation and amblyopia, a condition where one eye becomes weaker due to lack of use.

-'''Ocular dominance''', also known as '''eye preference''' or '''eyedness''', refers to the tendency to prefer visual input from one eye to the other. It is somewhat analogous to the laterality of right- or left-handedness, however, the side of the dominant eye and the dominant hand do not always match. This phenomenon has implications in [[neuroscience]] and [[optometry]].

-==Overview==
+'''Ocular dominance''', also known as '''eye dominance''', is the tendency to prefer visual input from one [[eye]] over the other. It is somewhat analogous to the [[handedness]] of an individual, although the side of the dominant eye and the dominant hand do not always match. Approximately two-thirds of the population is right-eye dominant, while the remaining one-third is left-eye dominant.

-Ocular dominance is measured on a continuum from strong left-eye dominance to strong right-eye dominance. Most individuals have a dominant eye, and it is especially noticeable when aiming, such as in shooting or archery. The dominant eye, called the '''fixating eye''', is the one that is primarily responsible for input to the visual cortex.
-==Neurological basis==
+==Physiology==
-The [[visual cortex]] of the brain, located in the occipital lobe, is the part of the brain that processes visual information. Within the visual cortex are ocular dominance columns, stripes of neurons in the visual cortex that respond preferentially to input from one eye or the other. The distribution of these columns is not even; in humans, there is a slight overall dominance of the right eye.
+Ocular dominance is a result of the brain's processing of visual information. The [[visual cortex]] in the [[brain]] receives input from both eyes, but the input is not always equal. The dominant eye sends stronger signals to the visual cortex, which can influence [[depth perception]] and [[binocular vision]].
-==Clinical significance==
+==Testing for Ocular Dominance==
-Understanding ocular dominance is important in predicting outcomes in treating certain conditions such as [[strabismus]] and [[amblyopia]], also known as lazy eye. In these conditions, the brain suppresses the image from the misaligned or weaker eye, leading to a loss of depth perception and binocular vision.
