Our eyes are very important to us. They are l cameras（照相机）. We can see beautiful things around us w our eyes. But if we don't take good care of them, we may not see clearly. H do we protect our eyes?
On a s day, the sun shines brightly. We should w our sunglasses. When we read, we shouldn't stay too close to our books and the light（光线）shouldn't be too bright or too weak. We s read in the bed. It is b for our eyes. We shouldn't play g on the computer for a long time either. We should have a rest after we use the eyes for a long time.
