Finally, you finish all your schoolwork and sit back in your chair. Suddenly you feel a headache and realize your eyes are painful. What’s going on? Doctors say that many students are spending too much time in front of screens(屏幕), especially during online classes. The following might be helpful to you.
THE 20-20-20 RULE This gives your eyes a break from long screen time. It suggests looking at something at least 20 feet away for 20 seconds after 20 minutes of work on the screen. You can then continue working pain free.	Studies show that people blink(眨眼睛) less often when looking at a screen. Keep your eyes wet by blinking often or using eye drops.
	Sit up straight about an arm’s length away from the screen. Make sure you’re looking down at your screen. Stand up and exercise often to avoid neck and shoulder pain.
	What about blue light blocking glasses(防蓝光眼镜)? They may look cool, but research shows that blue light isn’t the biggest cause of eye tiredness. So ask doctors about computer glasses before putting them on.
