Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Perceived Distance Optical Illusion

Below is an optical illusion that seems simple enough.

Which distance is longer? Is the distance between the tips of the first two opposing triangles pointing away from each other (A-B) on the left longer? Or is the distance between the points of the second two triangles facing each other (B-C) on the right longer?

Length optical illusions image

Which distance (tip to tip) is longer (A-B) or (B-C)?

You don't need me to tell you that it appears that the tips of the second two triangles (B-C) are further apart. It also seems that the tips of the first two triangles (A-B) are closer together.

If it was that easy though this image wouldn't be here would it? The truth is that the distance between the two sets (A-B) and (B-C) are exactly the same.

Go ahead get out your fine point marker and a ruler and see for your self, you know you want to. BTW don't use a Sharpie.
