科学家说眨眼20秒可以缓解用计算机的人眼疲劳。
马克研究人员想出了一个简单的锻炼方法,他们称可以缓解用计算机的人眼疲劳。
他们说每次连续眨眼20下,每20分钟视线离开屏幕看别处20秒,向20英尺远的地方望一望。
设计“20-20-20-20”对策招数来解决电脑视觉综合症问题,数以百万计的工人和游戏成瘾的人都有这种症状。

科学家称每次连续眨眼20下,应该每20分钟视线离开屏幕看别处20秒,看一看距离20英尺远的物体
这种症状如眼睛干燥、疲劳、头痛、关节痛、脖子酸痛,通常这些症状都是暂时性的,但日常这些问题日积月累就得求医治疗。
每天在电脑前坐三个小时以上的那些人最危险,代价就是导致许多人佩戴近视眼镜。
西南得克萨斯大学医学中心研究员爱德华·麦德森表示尽管这种做法可能看起来有点奇怪,但坚持定时眨眼可以起到帮助作用。
他说:“用电脑的人每20分钟应该休息20秒,向20英尺远的地方看一看。”
眨眼20下,眨眼是保持眼眶湿润的一种自然方式,眨眼有助于眼睛润滑和视力重新恢复。
在现代办公大楼的非自然条件下的无菌环境中长时间坐在屏幕前是不利健康的。

专家说这个建议可以帮助缓解盯了一天电脑屏幕后的眼疲劳
门德尔松博士补充说:“如今的办公室环境通常凉爽干燥、漂亮舒适但对眼睛健康影响不利。”
研究人员说开始工作之前滴眼药水能缓解眼睛干涩,一个姿势坐太久应离开屏幕休息一下还有利于脖子、肌肉其他部位的健康,缓解一下头痛问题。

The simple solution to screen fatigue: Scientists say 20 seconds of BLINKING can stop computer users getting eye strainBy Mark PriggResearchers have come up with a simple exercise they claim could stop computer users getting eye strain.They say blinking 20 times in a row every 20 minutes should be combined with looking away from the screen for 20 seconds and focusing on an object 20 feet away.The '20-20-20-20' strategy has been designed as a solution to computer vision syndrome (CVS) which affects millions of workers and games addicts.
Scientists claim blinking 20 times in a row every 20 minutes should be combined with looking away from the screen for 20 seconds and focusing on an object 20 feet away
THE 20-20-20-20 SYSTEMThe strategy is simple.Blinking 20 times in a row every 20 minutes should be combined with looking away from the screen for 20 seconds and focusing on an object 20 feet away.Symptoms such as dry and tired eyes, headaches and sore necks and joints are usually temporary but for many can be a daily problem that leads them to seek medical help.
Those most at risk are anyone who spends three or more hours a day in front of a computer, but it can be painful and lead to many being prescribed glasses.But although it may look a bit odd, a regular bout of blinking could help, said researcher Dr Edward Mendelson from the Southwestern Medical Centre at the University of Texas.  
He said: 'Every 20 minutes the computer user should take a break for 20 seconds and look at objects that are 20 feet away.

'And give yourself 20 good blinks - blinking is nature's way of keeping the eyes moist and those blinks help to lubricate and refresh.'Anyone who spends long periods in front of a screen is at risk but it is often worse for workers because of the sterile and unnatural conditions in modern office blocks.
Experts say the advice could help those who suffer from eye strain after a day staring at a computer screenDr Mendelson added: 'Today's offices are commonly cool and dry, which is nice and comfortable, except for the eyes.'
Eye drops taken before work begins can help with dry eyes but a break from a screen can also help with the other elements of CVS like neck, muscle and headaches from being sat in one position for too long, researchers say.
