①Eyes are important to us.We use them to read books,see colors and the beauty of the world,so we must keep our eyes healthy.But today there are more and more people having eye problems.This is because of their bad eye habits,like watching TV too long and reading books in bed.But don't worry.Here are some useful ways to protect (保护) our eyes.
②First,try to use our eyes in a right way.When we read books,we must keep our eyes 0.3 meters away from the book.When watching TV,we must keep a light on in the room.Try not to use smart phones in the sun.Spend less (更少的) time in front of screens.One or two hours a day is OK for your eyes.
③Second,find out what is the best food to keep eyes healthy.Milk,fruit and vegetables are good for our eyes,because they have much vitamin A,C,D and E.Also,sea fish and other seafood (海鲜) are helpful to eye health.And according to a new study,having unhealthy (不健康) food like ice—cream and Coke for a long time can even make us lose our eyesight (视力).
④What's more,we should also know what to do when we have eye problems.If our eyes get hurt,go to the doctor right away,Blink (眨眼) often and this can help us stop dry eyes.If we get something into our eyes,don't rub (揉) them with our hands.Try to use clean water to wash them.
⑤We only have one pair of eyes.Without (没有) good eyes,we will lose a lot of fun in life.So,let's try our best to keep them healthy.
