We know too bright light may hurt (伤害) people’s eyes. If you read in the sun, the book can reflect the bright sunlight into your eyes. It will hurt your eyes and make your eyes get tired easily.

Don’t read in bed or while lying on the Sofa. You should sit straight up and keep the book away from your eyes for about a foot.

After reading for a long time, try to close your eyes and do eye exercises, or have a rest by looking in the long distance (距离), especially after you work on the computers. Also, remember not to touch (触摸) your eyes with your dirty hands. If something is wrong with your eyes, go to see the doctor at once.
