Can you believe everything you see? Not always! You may see something one way, and then find out you were wrong. You might even "see" something that isn't there at all. Errors like these are called optical illusions. Optical means related to sight, or vision―the way we see things with our eyes. An illusion is something that is not what we think it is.

Vision is also a personal thing. You may not see things in the same way as someone else. Look at these optical illusions, and compare what you see with your classmates. Do you see the same things?

1、Which red dot is larger?
Most people say it's the dot on the left. Now measure the dots. They're the same size. The red dot on the left seems larger in relation to the blue dots around it.

2、Do you see dark dots inside the white circles?
They're not really there.The difference between the dark squares and the white circles confuses your brain. Therefore, your brain thinks you see the dark dots.

3、Look at this picture of a vase. Can you see the faces?
Look again! Your mind has to choose the correct image, so it keeps changing between the vase and the faces.

Vision is not always straightforward. Sometimes, your eyes see something, and your mind undestands it easily. At other times, you may need to look twice. When this happens, you may be seeing an optical illusion.
