Look at the center circles(中心圆) of picture A and picture B. Which of the center circles looks larger? Take a first look and you probably think that the center circle in picture A is smaller than that in picture B. In fact, they are exactly the same size.
Then look at the picture on the right. What do you see? A vase? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.
“What's happening? Is something wrong with my eyes?” You may ask yourself. Don't worry. Here is how it goes: When we look at things, our eyes send messages to our brains and then our brains interpret(解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it visual illusion(视觉错误).
Movie makers often make use of illusions. They make the things around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park(《侏罗纪公园》)and Honey, I Shrunk the Kids(《亲爱的，我把孩子变小了》) just make use of illusions.
