英语沙龙:防止电脑引起的视疲劳(在线收听) |
Prevent computer eyestrain Sit at least 20 inches away from the screen, and place it at or slightly below eye level. Follow the 20/20/20 rule:every 20 minutes, focus on something at least 20 feet away for 20 seconds. Post a reminder near your screen that says BLINK. Research shows we blink far less often when staring at a computer, and that’s a major contributor to eyestrain. 防止电脑引起的视疲劳 坐在距离电脑显示屏至少20英寸的地方。显示屏应放在与眼睛平行或略低于眼睛的位置。 遵循20/20/20规则:每隔20分钟, 花20秒钟的时间, 将注意力集中于至少20英尺以外的东西。 在显示屏旁边贴一张纸, 写着“眨眼睛!”来提醒自己。研究表明, 当我们盯着电脑的时候, 我们眨眼睛的次数太少了。这是引起视疲劳的主要原因。 |
