OPTICAL ILLUSIONS

Optical Illusions, more appropriately known as visual illusions, involve visual deception. Due to the arrangement of images, the effect of colors, the impact of the light source, or other variables, a wide range of interesting visual effects can be seen.

If you've ever struggled to see the hidden image in a single-image stereogram, you may have discovered that not everyone experiences visual illusions in the same way. For some illusions, some people simply are not able to see the effect.

Optical illusions can be fun and fascinating, but they can also tell us a great deal of information about how the brain and perceptual system function.
