It is said that the eyes are the windows of our soul． Beautiful and bright eyes not only show a good health but also make you look very attractive． However， to have healthy eyes you have to look after them properly． Your eyes need everyday attention．
Pay more attention to your diet． First， eat food that is good for your eyes． They are fresh fruits and vegetables as fish， eggs， and milk． Besides， a regular amount of vitamins A and B2should also be taken．
A regular and sound sleep is a must． It relaxes the eye muscles（肌肉）and gives them the rest required． Sleep not only helps the body to repair its tired tissues （组织）． Usually， you must sleep for at least seven to eight hours every day． Loss of sleep can give you dark circles under the eye．
You must exercise your eyes every day． Blink （眨眼） yours eyes at regular periods， which makes the eyeballs watery， and gives them a good wash．
We use our eyes in many unnoticeable and wrong ways． Fox example， if a small thing goes into our eye we start rubbing it， which is wrong． Rubbing can cause damage（伤害） to your eyes． Don't read or write in poor or bright sunlight． Always use sunglasses as sunlight can cause eye tiredness． Light should not shine directly in your eyes． Too much reading， writing， watching television or working on the computer can also cause eye tiredness．
Remember to always take care of God's most beautiful gift to you． Your life will be very colorless without your eyes．
