受新冠肺炎疫情影響，許多職場人士居家辦公，遠程處理工作事務，長時間使用電腦、手機。有人甚至表示，居家辦公比上班還累，因為根本沒有下班的時候。

眼科專家表示，這種情況下，合理用眼顯得更加重要。

A break of 10 minutes is necessary to relax the eyes after working continuously for 30 minutes to an hour, said Wei Wenbin, head of the ophthalmology department with Beijing Tongren Hospital, noting that remote working requires looking at screens for a long time, which could lead to eyestrain.
北京同仁醫院眼科主任魏文斌表示，遠程工作需要長時間看屏幕，由此導致眼睛疲勞，應該在連續工作30分鐘到1小時后讓眼睛休息10分鐘。

He called for a distance of 40 cm from computer screens during work and proper background light to reduce eye fatigue.
他還建議，工作時要與電腦屏幕保持40厘米的距離，同時保證有適當的背景照明，以緩解眼睛疲勞。

【知識點】

這里的eyestrain和eye fatigue均表示“眼睛疲勞”，有時eyestrain也寫作eye strain，常見的眼睛疲勞癥狀有：眼睛發熱或發癢（burning eyes or itchy eyes）、眼睛紅腫（sore or irritated eyes）容易流淚（watery eyes）、視線模糊或重影（blurred or double vision）、眼睛對光敏感（sensitivity to light），以及肩頸背痛（pain in the neck, shoulders, or back）等。

魏文斌建議，

People should ensure adequate sleep of seven to eight hours each night and exercise at home, including yoga, jogging, or sit-ups, said Wei, adding that computer keyboards should be cleaned regularly to prevent conjunctivitis caused by bacteria.
人們應該保證每晚7到8小時的睡眠，在家也要鍛煉身體，比如：瑜伽、慢跑或仰臥起坐等，此外，要定期清潔電腦鍵盤，以防止由細菌感染導致的結膜炎。

此外，健康網站上也列出了一些小貼士。

Looking away from the computer screen up to a distance of 20 feet for 20 seconds every 20 minutes helps in reducing the stress in the eyes.
看屏幕20分鐘后，抬頭眺望20英尺（6米）外的遠處至少20 秒鐘以上有助于緩解眼部壓力。

Firmly massaging the temples with your fingers in a rotary fashion for a minute while closing your eyes is often helpful in relieving the symptoms.
閉上眼睛，用手指在兩邊太陽穴用力揉圈按摩通常會緩解眼睛疲勞。

Repeated blinking eye exercise should be done for 10 seconds at least 5 times a day.
每天5次，每次10秒鐘做頻繁眨眼練習。

Changing brightness and contrast levels on your monitor and increasing text size can also be advantageous.
調整顯示器的亮度和對比度以及將屏幕上顯示的字體調大也會有幫助。
