(1)注意用眼卫生: 长时间使用电脑容易引起视觉疲劳。操作电脑时眼睛与文稿及屏幕两者的距离最好相等,距离应在50厘米以上。另外,电脑屏幕上如果反射出窗户的明亮影象,也会造成眼部的疲劳。这是因为当文字图象衬在一个很明亮的背景时,人眼要想分辨清楚,势必造成视神经的高度紧张。所以,使用电脑者身后如有窗户,应挂上窗帘;当头顶上或旁边如有台灯,应设法调整与电脑间的位置,避免强光直接照射到屏幕上。
(1) pay attention to eye health: prolonged use of the computer easily lead to visual fatigue. When operating the computer, the distance between the eyes and the document and the screen should be the same, the distance should be more than 50 centimeters. In addition, if the computer screen reflects the bright image of the window, can also cause eye fatigue. This is because when the text image lined a very bright background, the human eye to distinguish clearly, is bound to cause a high degree of nervous tension. Therefore, the use of computers behind the windows if any, should be hung curtains; when overhead or next to a lamp, should try to adjust the position between the computer to avoid glare directly to the screen.
