The contrast and color are the types that you can see more than one way such as the Necker cube.
Distortion is an illusion that appears as if it is changing size or shape off in the distance.
Typography illusions are the type you look at it one way and it may look like a B but in the other way it could be a 13. After effects are when you look at one thing then look at something else and the image will change. Illusions are used in many different ways. One is used by a ventriloquist so they can use their voice with the movement of the dummy s mouth and it tricks our brain into thinking that the dummy is talking. The people of Ancient Greece used optical illusions to build their temples by making the columns bulge so that from a distance they would look the perfectly proportioned.
