Optical illusion personality tests are simple, fun, and engaging tests that claim to reveal a person’s true nature, which might be hidden otherwise. As the name suggests, these are weird-looking images with one or more elements that trick the eyes. Depending on what catches a person’s attention first, a lot can be decoded about their true personality in just a few seconds.
