常用辭彙

Accommodation
調節
A process when our eyes need to change focus in order to see clearly at near.
當眼睛需要透過對焦才可以看清物件的程序。
Amblyopia
弱視
An eye disorder characterized by an impaired vision in an eye without apparent internal or external organic defects. In amblyopia, visual stimulation either fails to transmit or is poorly transmitted through the optic nerve to the brain for a continuous period of time which leads to poor vision.
視覺未有正常發展,但眼球内部、外部均外無器質性病變。視像長時期未能透過視神經傳達至大腦或傳達質量較差,大腦最終會放棄了該部份的視力功能,結果令視力減退,形成弱視。
Astigmatism
散光
A refractive error of the eye in which parallel rays of light from an external source do not converge on a single focal point on the retina.
當外部光線進入眼睛後,未能在視網膜上會聚集成單一焦點。

Computer Vision Syndrome (CVS)

電腦視覺綜合症

A term to describe these eye problems, and may affect up to 90% of computer users, whose symptoms may include asthenopia (eyestrain), headaches, dry eye, diplopia (double vision) and blurred vision after prolonged use (>1 hour) of computer or other digital screen devices.

描述眼睛問題的一個術語,可能 90% 的電腦用戶均受此症影響,長時間使用電腦或其他數碼螢幕設備後的症狀包括眼疲勞(視疲勞)、頭痛、乾眼症、複視(雙重影像)和視力模糊。

Concave lens

凹透鏡

A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).

凹透鏡鏡片的中心厚度比周邊的薄,可用來協助矯正因受近視影響的視力。

Convergence

會聚

The simultaneous inward movement of both eyes toward each other, usually in an effort to maintain single binocular vision when viewing an object.

在觀察物體時,雙眼同時向內移動,以保持雙眼單視的狀況。

Convex Lens

凸透鏡

A convex lens is bigger at its centre in comparison to its edges and is applied in correcting long-sightedness (hyperopia). 凸透鏡鏡片的中心厚度比周邊的厚,可用來協助矯正因受遠視影響的視力。

Cornea

角膜

The transparent anterior part of the external coat of the eye covering the iris and the pupil and continuous with the sclera.

一塊位於虹膜和瞳孔外部並連接鞏膜的透明部分。

Dry eye

乾眼症

An eye disease caused by eye dryness, which in turn, is caused by either decreased tear production or increased tear film evaporation.

眼淚的數量不足或者質量差,導致眼部乾燥的綜合症。

Esotropia

內斜視

Strabismus in which one eye deviates inward.

向前直望時,其中一隻眼向內傾斜。

Exotropia

外斜視

Strabismus in which one eyes turn outward.

向前直望時,其中一隻眼或雙眼向外傾斜。

Farsightedness

遠視

Seeing objects at a distance more clearly than those near at hand; hyperopic.

看較遠物件時會比看近物更清楚。

Hyperopia

遠視

Same as Farsightedness. Seeing objects at a distance more clearly than those near at hand; hyperopic.

看較遠物件時會比看近物更清楚。

Hypertropia

上斜視

Upward deviation of the visual axis of one eye.

向前直望時,其中一隻眼向上斜稱為上斜視。

Hypotropia

下斜視

Downward deviation of the visual axis of one eye.

向前直望時,其中一隻眼向下斜稱為下斜視。

Iris

虹膜

A thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.

眼睛中一個薄而呈圓形的結構,負責控制瞳孔的直徑和大小與進入視網膜的光量。

Lazy eye

弱視

Same as Amblyopia. An eye disorder characterized by an impaired vision in an eye without apparent internal or external organic defects. In amblyopia, visual stimulation either fails to transmit or is poorly transmitted through the optic nerve to the brain for a continuous period of time which leads to poor vision.

視覺未有正常發展,但眼球内部、外部均外無器質性病變。視像長時期未能透過視神經傳達至大腦或傳達質量較差,大腦最終會放棄了該部份的視力功能,結果令視力減退,形成弱視。

Lens

晶狀體

A transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.

為一個雙凸面透明組織,伴隨角膜,把光線折射並聚焦在視網膜上。

Macular

黃斑

An oval-shaped highly pigmented yellow spot near the centre of the retina of the human eye.

接近視網膜中央的一個橢圓形高色素的黃色斑點。

Myopia

近視

Same as Nearsightedness. Seeing distinctly at a short distance only; myopic.

只能清楚地看到短距離的物件。

Nearsightedness

近視

Seeing distinctly at a short distance only; myopic. 只能清楚地看到短距離的物件。

Optic Nerve

視神經

Nerve that transmits visual information from the retina to the brain.

負責從視網膜傳遞視覺信息到大腦的神經線。

Photoreceptors

感光體

Photosensitive cells in the retina stimulated by light.

會接受光線刺激的感覺器官。

Pupil

瞳孔

A hole located in the centre of the iris of the eye that allows light to enter the retina.

虹膜前的一個小孔,負責讓光線進入視網膜。

Refractive Errors

屈光不正

This is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity.

這是光線在眼內聚焦出現誤差的情況,亦是其中一個令視力下降的常見原因。

Retina

視網膜

The innermost coat of the posterior part of the eyeball that receives the image produced by the lens, is continuous with the optic nerve, and consists of several layers, one of which contains the rods and cones (photoreceptors) that are sensitive to light.

視網膜位於眼球最後的部分,它接收從晶狀體所產生的影像,並與視神經連接,它由多層組織組成,其中一層含有可以感受光的視桿細胞和視錐細胞。

Strabismus

斜視
