Our eyes is the most important contact window to communicate with outside for us. We should be careful to protect our eyes, so we should follow these things: be rest for a while after we see book or TV etc. for over an hour time; Every day we should keep practicing eye exercises; Our eyes should keep 30 cm distances from the book; Please don’t read under weak light. If we can do above things, our eyes will be good. I hope all of us have good eyes and can see more beautiful views.
