Computer Vision Syndrome (CVS)

电脑视觉综合症

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.

描述眼睛问题的一个术语，可能 90% 的电脑用户均受此症影响，长时间使用电脑或其他数码萤幕设备后的症状包括眼疲劳（视疲劳）、头痛、干眼症、复视（双重影像）和视力模糊。

Concave lens

凹透镜

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

凹透镜镜片的中心厚度比周边的薄，可用来协助矫正因受近视影响的视力。

Convergence

会聚

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

在观察物体时，双眼同时向内移动，以保持双眼单视的状况。

Convex Lens

凸透镜

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.

一块位于虹膜和瞳孔外部并连接巩膜的透明部分。

Dry eye

干眼症

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

眼泪的数量不足或者质量差，导致眼部干燥的综合症。

Esotropia

内斜视

Strabismus in which one eye deviates inward.

向前直望时，其中一只眼向内倾斜。

Exotropia

外斜视

Strabismus in which one eyes turn outward.

向前直望时，其中一只眼或双眼向外倾斜。

Farsightedness

远视

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

看较远物件时会比看近物更清楚。

Hyperopia

远视

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

看较远物件时会比看近物更清楚。

Hypertropia

上斜视

Upward deviation of the visual axis of one eye.

向前直望时，其中一只眼向上斜称为上斜视。

Hypotropia

下斜视

Downward deviation of the visual axis of one eye.

向前直望时，其中一只眼向下斜称为下斜视。

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.

眼睛中一个薄而呈圆形的结构，负责控制瞳孔的直径和大小与进入视网膜的光量。

Lazy eye

弱视

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.

视觉未有正常发展，但眼球内部、外部均外无器质性病变。视像长时期未能透过视神经传达至大脑或传达质量较差，大脑最终会放弃了该部份的视力功能，结果令视力减退，形成弱视。

Lens

晶状体

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

为一个双凸面透明组织，伴随角膜，把光线折射并聚焦在视网膜上。

Macular

黄斑

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

接近视网膜中央的一个椭圆形高色素的黄色斑点。

Myopia

近视

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

只能清楚地看到短距离的物件。

Nearsightedness

近视

Optic Nerve

视神经

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

负责从视网膜传递视觉信息到大脑的神经线。

Photoreceptors

感光体

Photosensitive cells in the retina stimulated by light.

会接受光线刺激的感觉器官。

Pupil

瞳孔

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

虹膜前的一个小孔，负责让光线进入视网膜。

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.

这是光线在眼内聚焦出现误差的情况，亦是其中一个令视力下降的常见原因。

Retina

视网膜

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.

视网膜位于眼球最后的部分，它接收从晶状体所产生的影像，并与视神经连接，它由多层组织组成，其中一层含有可以感受光的视杆细胞和视锥细胞。

Strabismus

斜视

A disorder of vision due to a deviation from normal orientation of one or both eyes so that both cannot be directed at the same object at the same time; squint; crossed eyes.

是视觉上的失调，原因一只眼或双眼有视觉上的偏差，导致眼睛未能够同时瞄准同一事物。

Visual Cortex

视觉皮层

The portion of the cerebral cortex of the brain that receives and processes impulses from the optic nerves.

从视神经接收和处理脉冲的大脑皮质的部分。
