What is eye dominance?

eye dominance or eye dominance refers to the tendency to prefer the visual input of one eye compared to the other eye. This is also called "eyes", using this word similar to the use of "handedness". About two -thirds of the general population have the real dominance of the eyes, while the remaining one third has the dominance of the left eye. Some people have not left eye dominance or true eye dominance. In the right brain hemisphere, the right hand is controlled by the right brain hemisphere, while the left brain hemisphere controls the right hand. Most people have left the dominance of the brain and the right hand. The laterality of the dominant hand and the laterality of the dominant eye does not always agree, because both left and right brain hemispheres control both eyes, but take over different halves of both retina. Dominance can change according to the view direction because it causes a change in the size of the retina image.

Eye dominance can be classified as weak or strong. Among people with very strong eye dominance there is usually a basic eye disease such as strabismus orAmblyopia. In strabism, the eyes are incorrectly aligned, so in each particular case only one eye considers the object of respect. Unleashed or dominant eye often develops reduced visual acuity or amblyopia despite the absence of detectable disease.

In sports that require accuracy, such as darts, archery and shooting, one relies primarily on the dominant eye for the right goal. Cross-dominance, a phenomenon in which the hand on the side opposite the dominant eye is a factor that improves performance in sports such as Golf, Baseball or cricket. However, there is no definitive evidence of this theory.

Eye dominance tests include Miles Aunt, Porta Test, Dolman Method, or tab -tab test, convergence test close point, lens fogging technique and camera test. Dolman's method is a test of dominance of forced selection and allows only the result of the left eye or the right eye,Which means that it inefficiently does not determine whether a person has dominance. An objective test of eye dominance is a convergence close test where the tested person determines his eyes on an object moving towards the nose until the eye is no different. Knowledge of human dominance is important in calibrating the contact lens, refractive surgery and surgery of cataracts, which aimed at correction of monovision.
