How to Prevent Computer Eyestrain
怎样避免电脑引起的视觉疲劳
Computer eyestrain can hurt productivity, but it's easy to prevent if you take a few precautions.
Steps 步骤
STEP 1 Turn down the lights 将亮度调低
Close the blinds and turn off extra lights to reduce glare.
Use an anti-glare screen or computer hood if you can't reduce the light in your office. Buy an LCD monitor, since older CRT monitors produce flicker, a major source of eyestrain. Use a monitor measuring at least 19 inches with a dot pitch of .28 millimeters or lower.
If you're stuck with a CRT monitor, set the refresh rate as high as possible to reduce flicker.
STEP 3 Look away 时不时转移一下视线
Look out a window or down a hall. Break up computer work by focusing on a distant object every twenty minutes.
STEP 4 Blink more 多眨眼
Blink to keep your eyes moist. Blink 10 times, slowly, every half hour.
STEP 5 Use a copy stand 使用复制架
Use a copy stand and place it next to your monitor to reduce the distance your eyes must travel between page and screen.
Make sure printed materials are well lit, but don't shine a lamp on the screen or in your eyes.
STEP 6 Use computer glasses 选用计算机眼镜镜片
Use computer glasses, which are designed specifically for the distance between your eyes and the computer screen.
Computers with Braille displays are available for the sight-impaired.
