Today more and more children wear glasses before going to middle school. They keep their eyes watching TV or playing computer games for a long time. Eyes are the windows of our hearts (心). We use our eyes to see everything around us, so we should know how to protect our eyes.

    Love our eyes. When we open (睁开) our eyes every day, we can see the lovely friends and parents, beautiful flowers and green trees. If our eyes don't work, how can we see the world. In our eyes, everything and everywhere is dark. It's like a house with no light (光). How important our eyes are!

    Relax our eyes. First, stop to relax 30 minutes when using the computer for an hour or two. Next, remember to do eye exercises every day. Then, looking at green trees also helps a lot. In these ways, our eyes will feel relaxed.

    Have good habits. When writing homework and reading, it is important to keep a distance (距离) of 30 cm between your eyes and books. Remember to use our eyes in a right way. Don't read in bed or on a moving bus. Eat something healthy for eyes, such as carrots, fish and eggs.

    Follow my advice (建议) and get good habits. It's time to say goodbye to thick (厚的) glasses.
