Ocular dominance. Ocular dominance, sometimes called eye preference or eyedness, [ 1] is the tendency to prefer visual input from one eye to the other. [ 2] 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. [ 3]
assess degree of binocular vision. The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a ...
The Punnett square is a visual representation of Mendelian inheritance, a fundamental concept in genetics which is discovery of Gregor Mendel. [ 10] For multiple traits, using the "forked-line method" is typically much easier than the Punnett square. Phenotypes may be predicted with at least better-than-chance accuracy using a Punnett square ...
Ocular dominance column. Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans [ 1]) that respond preferentially to input from one eye or the other. [ 2] The columns span multiple cortical layers, and are laid out in a striped pattern across the surface of the striate cortex (V1).
Color blindness or color vision deficiency ( CVD) is the decreased ability to see color or differences in color. [ 2] The severity of color blindness ranges from mostly unnoticeable to full absence of color perception. Color blindness is usually an inherited problem or variation in the functionality of one or more of the three classes of cone ...
An epicanthic fold or epicanthus[ 6] is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. [ 3] However, variation occurs in the nature of this feature and the possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature. [ 7][ 8][ 9] Various factors influence ...
Once the fields of view overlap, there is a potential for confusion between the left and right eye's image of the same object. This can be dealt with in two ways: one image can be suppressed, so that only the other is seen, or the two images can be fused. If two images of a single object are seen, this is known as double vision or diplopia.
The term "binocular disparity" refers to geometric measurements made external to the eye. The disparity of the images on the actual retina depends on factors internal to the eye, especially the location of the nodal points, even if the cross section of the retina is a perfect circle. Disparity on retina conforms to binocular disparity when ...
