Nowadays, we are having a much busier life, and we are using our eyes more than ever before. So we often have tired eyes after a day’s work or study. Here are some good methods of protecting eyes against tiredness to keep them healthy.

POSTURE（坐姿）

 Get into the habit of paying attention to the way you sit. Try to stick to the proper posture that doctors suggest.

HELPFUL PICTURES

There are some special pictures online that can help relax your eyes. You may download such pictures to your computer or smart phone. When there is nothing far away you can look at to relax your eyes, you can use one of these pictures. A picture with something like a tunnel（隧道）in it is quite popular. Try to look as far into the tunnel as you can for 30 seconds（秒）. Do you feel better?

BREAKS
The 20-20-20 rule: take a break from the screen every 20 minutes for 20 seconds and look at something 20 feet（about 6 meters）away.
EYE EXERCISES

Step 1. Sitting comfortably, imagine there is a clock in front of you and turn your eyes up to 12 o’clock. Pause（停顿）for a second, and then lower your eyes to 6 o’clock. Pause again, and then repeat this step 10 times. Complete the exercise by cupping your hands over your eyes for a few seconds, letting them rest in the darkness.

Step 2. Look at something on the right. Keep your eyes on it and slowly turn your head to the left as far as possible. Then do the same thing on the left. Repeat the exercise a couple of times.

Step 3. Hold your finger in front of your nose and keep looking at it. Slowly move the finger towards yourself as close as you can without losing focus（焦点）. Then look outside the window as far as possible. Repeat this several times.

SPORTS
Table tennis is about a small ball traveling at high speed—the best sport to train your eyes and relax the muscles（肌肉）in and around the eyes. Other sports like tennis, badminton and kite flying are also great for relaxing tired eyes.
