But when it is combined with excessive computer use, that risk rose to around 80 percent.研究人员发现，长时间盯着手机或平板电脑会使患近视的风险增加约30%。但如果再加上过度使用电脑，这种风险将上升到80%左右。

Staring at a screen continuously for hours on end causes focusing fatigue. To avoid this, many eye experts recommend the “20-20-20 rule” – looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20ft away for at least 20 seconds. 连续数小时盯着屏幕会导致聚焦性眼疲劳。为了避免这一点，很多眼科专家推荐“20-20-20规则”，也就是每20分钟让眼睛离开手机或电脑屏幕，盯着20英尺（约合6.1米）外的物体看至少20秒。
