Distortion Illusions

Distortion illusions make an object look smaller, bigger, longer, shorter, or a different shape. This type of illusion may show you the word "life" and ask you if the lines are straight. (Hint: they are!)

Another famous illusion of this type is the "Which line is longer?" illusion seen below.

Some other famous illusions of this type are the Poggendorf illusion, the twisted cord illusion and the café wall illusion. To find out about these and others, click here.
