Optical illusions are images and photos that look one way but really are another way. They could also appear to be two things at the same time. Optical illusions trick the mind and the eye into seeing things that aren't really there. They take a second to figure out, and some are still nearly impossible to decipher. Some optical illusions have blown up the internet over the years, such as the brick wall and the dress.

People see optical illusions differently, making them fun to share around. Optical illusions can be found anywhere, sometimes all it takes is someone being in the right place at the right time.
