Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks
larger? 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 wonder at what you see. 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 visual illusions. They
make the objects 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 and Honey I shrunk the kids just make use of visual
illusions.
