In terms of the visual cortex, this has been confirmed in studies on perceptual learning, noninvasive brain stimulation, and short-term monocular deprivation. Ample evidence shows the adult brain retains a degree of neural plasticity. This approach harkens back to the concept of cortical plasticity corroborated in experiments on the kitten deprived of vision in one eye, and it also works in adults.

Patching is the standard therapy for children with amblyopia (lazy eye), in which the вЂњgoodвЂќ eye is patched to improve vision in the weaker eye. It also applies to photography because using the dominant eye to look through the viewfinder has obvious benefits on focus and composition. Interestingly, the dominant eye also matters to clinicians who use monocular instruments such as the microscope and ophthalmoscope. Sight in the dominant eye is less easily suppressed by the relatively blurred image in the non-dominant eye. In a вЂmonovisionвЂ™ approach, the dominant eye is typically corrected for distance and the other eye for near vision. It is important in cataract, refractive, and laser eye surgery, as well as contact lens wear. Knowing which eye is dominant has other practical applications. Aiming is harder than it should be and youвЂ™ll notice the tendency to turn your head to see out of your left eye. LetвЂ™s say you begin shooting archery as a right-eye shooter, but you are left-eye dominant. Shooting a bow that is the reverse of your eye dominance can be frustrating. If you are left-eye dominant, you draw with your left hand. For example in archery, if you are right-eye dominant, you draw the string with your right hand. Knowing which eye dominates can help an athlete achieve better head and eye positioning while hitting a baseball or shooting a basket. Knowing which eye is dominant is useful in sports such as shooting, archery, bow-hunting, darts, baseball, golf, cricket, and basketball. The work of Nobel Prize winners David Hubel and Torsten Wiesel greatly expanded scientific knowledge of visual processing. This concept has been confirmed in more recent research by Jonathan Pointer, who also showed an individualвЂ™s handedness is not predictive of eye dominance. He discovered an inter-ocular difference in vision, meaning the eye with the better vision is not necessarily the dominant eye. He claimed most individuals have a dominant eye, even when the vision of both eyes is equal. Rosenbach is credited with being the first author to refer to eye dominance in a German publication, back in 1903. Despite these odds, handedness alone is not an accurate predictor of eye dominance. Although they are not linked scientifically, population studies indicate about 90% of people are right-handed, and of those, 67% are right-eye dominant. A common question is whether eye dominance and handedness (being right-handed or left-handed) are connected.

Most people tend to have a dominant eye so that even when both eyes are open, one is processing visual input more than the other. The brain processes and builds images using slightly different views from the right or left eye. Most people are unaware they favor one eye for visual input. Ocular dominance (also called eye preference) refers to visual preference in one eye over the other.
