| 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. |

| 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) |
