Look at the center circles of Diagram (圖) A and Diagram B.  Which of the centre circles looks larger? 
Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram 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 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 (解讀) 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" (視覺錯(cuò)誤). 
Movie makers often make use of 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 illusions.

Look into the mirror and what do you see? You see yourself. But when you move. you do everything backward(相反地)in the mirror! If you wave your left hand, your right hand waves in the mirror. If you wink your right eye, your left eye, your left eye winks(眨). Try to read a page in the mirror .The words will be backwards.
What is really happening? You do not see through the glass of a mirror as you do through a window. The glass of a mirror has a silver coating on the back. The light from the sun or a bulb bounces (彈回)off you ,goes into the mirror ,and bounces straight back out to you again.
Mirrors have been used for thousands of years. The earliest were round pieces of shiny metal. Glass mirrors came late. The ancients thought that a mirror was magic. They did not understand how it worked. They thought they saw their spirits in a mirror and breaking a mirror brought bad luck.
Today mirrors have many uses .For example, they can make rooms look bigger and prettier. They also show us if our hair is combed(梳理) well and our faces are clean. On cars, buses and trucks, mirrors help drivers see traffic behind them. Mirrors are also used in telescopes(望遠(yuǎn)鏡)and searchlights(探照燈).
Fun houses use mirrors. They make people look funny. Some mirrors are curved to make people seem short and round or tall and tin They make people laugh at themselves
