Our eyes are very important（重要的）to us. They are like cameras（相机）. We can see beautiful things and colours around us with our eyes. But if we don't take care of（照顾）them, they may get hurt（受伤）. How can we protect（保护）our eyes? On sunny days, we'd better wear sunglasses. When we read, we shouldn't（不应该）stay too close（太近）to the books and the light shouldn't be too bright（太亮）or too dark（太暗）. We shouldn't read in bed. It's bad for our eyes. We mustn't read books on a bus or play games on the computer for a long time.
