Many of us don't pay much attention to eye care. Eyes are the window of the mind. We should give a lot of care to our eyes. Natural eye care should be put in the first place.
There are several causes leading to poor eyesight like not eating right kinds of food, genes (基因) and aging(老化). Watching too much TV, using computers for too long and reading too much are also the causes of having poor eyesight. If you have to work in front of a computer, you'd better take a break once in a while.
Some dirt(灰尘)can make your eyes red and it will make you feel uncomfortable. It is bad for your eyes too. If there is some dirt in your eyes, the best way is to clean your eyes by using clean water. You must also try your best to protect your eyes from harmful things. For example sunglasses are not just for fashion but they can also serve as a great way to protect your eyes from UV rays(紫外线)
Eating healthy food will be beneficial to your eyesight. Remember that vitamins(维他命)A, C and E are good for eyes. Try to cat food that has these vitamins. And you should do eye exercises because they help relax your eyes. If a person often does eye exercises and eats the right kind of food his eyes will probably stay in good condition.
All above are natural ways of eye care that help us protect our eyes. In a word, eye care is very important, no matter how old a person is.
