| vision disparity | The difference between two images on the retina when looking at a visual stimulus. This occurs since the two retinas do not have the same view of the stimulus because of the location of our eyes. Thus the left eye does not get exactly the same view as the right eye. (12 Dec 1998) |
| vision, entoptic | Visual sensation due to shadows or optical effects of structures within the eye or to excitation of the receptor system by stimuli other than light. (12 Dec 1998) |
| vision, monocular | Vision with one eye or the affecting of one eye. (12 Dec 1998) |
| vision screening | Application of tests and examinations to identify visual defects or vision disorders occurring in specific populations, as in school children, the elderly, etc. It is differentiated from vision tests, which are given to evaluate/measure individual visual performance not related to a specific population. (12 Dec 1998) |
| vision, subnormal | Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. (12 Dec 1998) |
| central vision | Vision stimulated by an object imaged on the fovea centralis. Synonym: direct vision. (05 Mar 2000) |
| peripheral vision | Vision resulting from retinal stimulation beyond the macula. Synonym: indirect vision. (05 Mar 2000) |

| coloured vision | A condition in which objects appear to be abnormally coloured or tinged with colour; designated according to the colour seen: xanthopsia, yellow vision; erythropsia, red vision; chloropsia, green vision; cyanopsia, blue vision. Synonym: chromatic vision, coloured vision, tinted vision. Compare: dyschromatopsia. Origin: chromato-+ G. Opsis, vision (05 Mar 2000) |
| colour vision defects | Mild to severe impairment in the ability to discriminate or differentiate hues. This disorder may be acquired as a result of diseases of the cones or x chromosome-linked where there is an abnormality but not a complete absence of one of the cone pigments. (12 Dec 1998) |
