| 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. |

| 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) |
|---|---|
| retinal disparity | The slight difference in retinal images that arises because of the lateral separation of the two eyes that stimulates stereoscopic vision. (05 Mar 2000) |
| disparity | The condition of being disparate. Origin: L. Dispar, dissimilar (05 Mar 2000) |
| disparity angle | The difference in position of images on the retina, still permitting fusion. (05 Mar 2000) |
| fixation disparity | The amount of heterophoria possible with fusion present. (05 Mar 2000) |
| binocular | 1. Having two eyes. "Most animals are binocular." 2. Pertaining to both eyes; employing both eyes at once; as, binocular vision. 3. Adapted to the use of both eyes; as, a binocular microscope or telescope. Origin: Cf. F. Binoculaire. See Binocle. A binocular glass, whether opera glass, telescope, or microscope.

| binocular fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| binocular heterochromia | An increase or decrease in pigmentation of one eye, with or without extraocular pigmentary defects. (05 Mar 2000) |
| binocular microscope | <instrument, microscopy> A microscope fitted with double eyepieces for vision with both eyes. The purpose in dividing the same image from a single objective of the usual compound micro-scope is to reduce eyestrain and muscular fatigue which may result from monocular, high-power microscopy. The purpose in obtaining a different image for each of two oculars is to provide stereoscopy by means of two different angles of view. There are two kinds of stereoscopic microscopes: binobjective (Greenough) older type and monobjective (common main objective) newer type. (See stereo microscope, Greenough microscope, etc.) (05 Aug 1998) |
| binocular ophthalmoscope | <instrument> An ophthalmoscope that provides a stereoscopic view of the fundus. (05 Mar 2000) |
| binocular parallax | The difference in the angles formed by the lines of sight to two objects situated at different distances from the eyes; a factor in the visual perception of depth. Synonym: stereoscopic parallax. (05 Mar 2000) |
| binocular rivalry | Alteration in perception of portions of the visual field when the two eyes are simultaneously and rapidly exposed to targets containing dissimilar colours or borders. (05 Mar 2000) |
| binocular vision | Vision with a single image, by both eyes simultaneously. (05 Mar 2000) |
| vision, binocular | The blending of separate images seen by each eye into one composite image. (12 Dec 1998) |
| monobjective binocular microscope | <instrument, microscopy> A microscope with one objective and two bodies, for binocular vision, not necessarily stereoscopic. (05 Aug 1998) |
