Rest Your Eyes: Level 1 Reading Comprehension Questions

Many people now spend hours looking at a screen. After a long day of it, the eyes can feel dry, tired, and sore. This happens partly because we blink less when we stare at a screen. We also hold our eyes at one short distance for too long.

There is a simple way to help, sometimes called the 20-20-20 rule. Every twenty minutes, look at something far away, about twenty feet, for twenty seconds. This lets the eye relax and change its focus. Blinking on purpose also helps, since it wets the eye again.

It helps to sit a little farther from the screen and to keep the room softly lit, not too bright or too dark. Your eyes were made to look near and far all day. A few short breaks give them the change they need.
