课文(一):缓解电脑前的“视觉疲劳”

眼睛发涩,有灼热感,看东西模糊,有时流泪,有时干痒,还经常头疼、脖子酸痛,这可能是长时间看电脑屏幕引起的“视觉疲劳”。

视觉疲劳是眼睛的一种亚健康状态,一般休息之后就可以缓解,但如果长期如此,也可能转变为眼部疾病,甚至会引发视网膜脱落、失明等。

下面几种方法,可以缓解电脑引起的视觉疲劳。

正确摆放屏幕位置。眼睛与屏幕要保持60厘米以上的距离,屏幕要适当放低,使眼睛能向下30度俯视屏幕,这样不但不累眼,还可以使颈部肌肉放松,改善脑部供血。

安排“中场休息”。在电脑前工作1~2小时后,一定要让眼睛放松15分钟左右,看看电脑屏幕以外的其他东西,比如桌上的其他物品、窗外的绿色植物等。

放松眼部肌肉。全身放松,双肘放在桌子上,手掌托,闭上双眼,深呼吸15~30秒钟。每天重复几次,可以缓解眼部肌肉紧张,减轻用眼疲劳。

合理饮食,补充营养。多吃一些蔬菜和水果,如胡萝卜、西红柿、橘子、香蕉等。另外,每天喝几杯绿茶,不但可以保护和提高视力,还能减轻电脑辐射的危害。

Text (1): relieving “visual fatigue” in front of the computer

The eyes are dry and itchy, have a burning hot feeling, things are fuzzy and with teary eyes, often have a headache and the neck is aching. This is likely to be the “visual fatigue” that comes with looking at a computer screen for a long time.

Visual fatigue is a sub-healthy state of the eyes, which can be relieved after a general rest. However, if it lasts for a long time, it may become a chronic eye disease and even cause retinal detachment, blindness, etc.

The following several methods can alleviate computer-induced visual fatigue.

Position the screen correctly. The distance between eyes and screen should be kept at more than 60cm. The screen should be properly lowered so that the eyes can look down at the screen at 30 degrees. Thus not only not resting the eyes, but also relaxing the muscles of the neck and improving the blood supply to the brain.

Arrange a “half-time”. After working in front of the computer for 1 or 2 hours, be sure to let your eyes relax for about 15 minutes and look at other things outside the computer screen, such as other objects on the table and green plants outside the window.

Relax the eye muscles. Relax your whole body, put your elbows on the table, hold your eyebrows in your hands, close your eyes, and take a deep breath for 15–30 seconds. Repeat several times a day, this can alleviate eye muscle tension and reduce eye fatigue.

Eat properly and supplement your nutrition. Eat more vegetables and fruits, such as carrots, tomatoes, oranges, bananas, etc. In addition, drinking a few cups of green tea every day can not only protect and improve vision, but also reduce the harm of computer radiation.
