Optical Illusions

We can't always trust what we see. We are used to how things are supposed to look. If pieces are missing, sometimes our brain fills them in. Our brain puts information together in a way that makes sense and allows us to see optical illusions in different ways. Optical illusions have been studied for thousands of years. The ancient Greeks even used the principles of optical illusion in their architecture.

Is it a Candlestick or Two Profiles

candlestick overThis image can be seen one of two ways, as a candlestick or a pair of identical profiles. It is very difficult for our minds to view the image both ways at the same time. Most people will either see the candlestick or the profiles, but not both.

Which do you see? Why?

 

Which Center is Larger?

Do You See a Triangle?triangle over

The triangle is an optical illusion that you see because of the angles of the three dark shapes.

When you look at this Ferris wheel, does it look like it is moving?

Which is larger – the white squares or the black squares?

Actually, all of the squares are the exact same size!

And the little white dots make the illusion of a ball in the middle – can you see it?

 

 

 

Who is taller?
