| 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. |

| pupillary light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |

| spectroscopy, near-infrared | A noninvasive technique that uses the differential absorption properties of haemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional haemodynamics and blood flow. Near-infrared light (nir) can propagate through tissues and at particular wavelengths is differentially absorbed by oxgenated vs. Deoxygenated forms of haemoglobin and myoglobin. Illumination of intact tissue with nir allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.

| near | 1. Not far distant in time, place, or degree; not remote; close at hand; adjacent; neighboring; nigh. "As one near death." "He served great Hector, and was ever near, Not with his trumpet only, but his spear." (Dryden) 2. Closely connected or related. "She is thy father's near kinswoman." (Lev. Xviii. 12) 3. Close to one's interests, affection, etc.; touching, or affecting intimately; intimate; dear; as, a near friend. 4. Close to anything followed or imitated; not free, loose, or rambling; as, a version near to the original. 5. So as barely to avoid or pass injury or loss; close; narrow; as, a near escape. 6. Next to the driver, when he is on foot; in the Unted States, on the left of an animal or a team; as, the near ox; the near leg. See Off side, under Off, . 7. Immediate; direct; close; short. "The nearest way." 8. Close-fisted; parsimonious. Near may properly be followed by to before the thing approached'; but more frequently to is omitted, and the adjective or the adverb is regarded as a preposition. The same is also true of the word nigh. Synonym: Nigh, close, adjacent, proximate, contiguous, present, ready, intimate, dear. Origin: See Near. Source: Websters Dictionary (01 Mar 1998) |
| near drowning | Any almost drowning. All cases should be evaluated by a physician. Complications include aspiration pneumonia and adult respiratory distress syndrome. (27 Sep 1997) |
| near point | That point in conjugate focus with the retina when the eye exerts maximal accommodation. Synonym: punctum proximum. (05 Mar 2000) |
| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| near point of the eye | <ophthalmology> The nearest point to the entrance of the pupil of the normal eye at which focus is attained without strain, 10 inches (250 mm) is the generally accepted distance. In very young people and in those with myopia, this distance is less. The near point recedes with age, possibly even causing farsighted condition,. (05 Aug 1998) |
| near reaction | The pupillary constriction associated with a near vision effort, i.e., with accommodation and convergence. (05 Mar 2000) |
| near reflex | Pupillary constriction with a near vision effort, with ocular convergence, or with accommodation; an associated reaction, not a true reflex. (05 Mar 2000) |
| near sight | <ophthalmology> That error of refraction in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back (axial myopia) or of an increased strength in refractive power of the media of the eye (index myopia). Also called nearsightedness, because the near point is less distant than it is in emmetropia with an equal amplitude of accommodation. Origin: Gr. Myein = to shut (18 Nov 1997) |
| near-total thyroidectomy | Removal of nearly all of each thyroid lobe leaving unresected only a small portion of gland adjacent to the entrance of the recurrent laryngeal nerve into the larynx. (05 Mar 2000) |
| far-and-near suture | A suture utilizing alternate near and far stitches, used to approximate fascial edges. (05 Mar 2000) |
| light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| achromatic vision | A severe congenital deficiency in colour perception, often associated with nystagmus and reduced visual acuity. Synonym: achromatic vision, monochromasia, monochromasy, monochromatism. Origin: G. A-priv. + chroma, colour, + opsis, vision (05 Mar 2000) |
| binocular vision | Vision with a single image, by both eyes simultaneously. (05 Mar 2000) |
| near vision | vision for objects 2 feet or closer to the viewer |
