| 영문 | binocular vision | 한글 | 두눈보기, 양안시 |
|---|---|---|---|
| 설명 | 좌우 양쪽의 눈으로 상을 보는 경우이며, 단안시에 대응하는 용어이다. 양쪽 눈을 이용해서 한 물체를 볼 경우엔 입체적으로 보인다. 양쪽 안구의 협조적인 작용에 의하여 양안으로 동일한 점을 주시하여 하나의 물체로 보게 된다. 단안시에 비하여 맹점을 보완하고 시력을 증대하며, 더욱이 공간의 퍼짐을 인지하거나 입체시를 보다 완전하게 할 수 있다. 포유류에서도 좌우 양안의 시축 각도의 벌어짐은 여러 가지로서, 사자는 10°, 개는 30~50°, 노루는 100°, 토끼는 170°이다. 정면의 물체는 양쪽 눈으로 볼 수 있으나 좌우 방향에 있는 물체는 양쪽 눈을 동시에 움직여 한족 눈으로 보는 것과 같은 경우가 많다. 육식동물은 양안시형이 많고, 설치류나 유제류와 같은 초식동물은 단안시형이 많다. 조류에서도 올빼미 등은 양안시형이고, 닭 등은 단안시형이다. |

| twilight | 1. The light perceived before the rising, and after the setting, of the sun, or when the sun is less than 18 deg below the horizon, occasioned by the illumination of the earth's atmosphere by the direct rays of the sun and their reflection on the earth. 2. Faint light; a dubious or uncertain medium through which anything is viewed. "As when the sun . . . From behind the moon, In dim eclipse. Disastrous twilight sheds." (Milton) "The twilight of probability." (Locke) Origin: OE. Twilight, AS. Twi- (see Twice) + leoht light; hence the sense of doubtful or half light; cf. LG. Twelecht, G. Zwielicht. See Light.

| vision disorders | Visual impairment limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, colour vision, or peripheral vision. Visual disability refers to inability of the individual to perform specific visual tasks, such as reading, writing, orientation, or traveling unaided. It is to be differentiated from eye diseases which are restricted to diseases of the eye, the organ and its anatomical parts. (12 Dec 1998) |
| 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) |
| twilight vision | the ability to see in reduced illumination (as in moonlight) |
