Optical illusions are mind blowing at any age. When you're a child, they make you question everything, and that doesn't exactly change when you're an adult. It's crazy to think how our minds and eyes work in different ways to play tricks on us, and make us see things that aren't actually there. Some illusions are all in the eyes, playing on your eyes' abilities and limitations, while others are due to the signals in the brain and its judgment calls. Either way, optical illusions seem to take us into a trippy dimension.
