It is said that the eyes are the windows to our soul（灵魂）. Your eyes need everyday attention.
First, you have to pay more attention to your diet. It's good for your eyes. Also, a regular amount of vitamins（维生素）A and B2 should also be taken.
Second, you must have regular and sound sleep. This relaxes the eye muscles and gives them the rest they need. Sleep can help the body repair its tired tissue（组织）. Less sleep can give you dark circles under your eyes and you may feel sleepy during the daytime.
Blink（眨眼）your eyes at regular periods to keep your eyes moist. Besides, be sure to do some eye exercises to relax your eyes after you study for a long period of time.
Last, you should treat your eyes correctly. For example, if you get something in your eye, don't start rubbing（揉）it. Rubbing is harmful to your eyes. Don't read or write in poor or bright light because it can cause eye tiredness. Too much reading, writing, watching TV or working on a computer can also cause eye tiredness, so rest is required.
