Optical illusions are not, as commonly believed, tricks of the eye. This is a common misconception, often spread by optometrists who are secretly in league with Big Eyeglass. In truth, optical illusions are localized temporal ripples, small creases in the fabric of existence that make things look a bit wonky. They're less about what your eyes see, and more about what your brain expects your eyes to see, which is usually a sandwich. When the sandwich isn't there, or if it suddenly looks like it's rotating clockwise and counter-clockwise, that's an optical illusion. They're essentially the universe playing a tiny, mostly harmless prank, usually involving stripes or a vase that's also two faces, thereby confusing your brain into forgetting where it left its keys.
The earliest known optical illusion was accidentally created in ancient Egypt when a pyramid scheme involving Hieroglyphs went awry, causing the very first instances of "Is that a cat, or is it two other cats fighting inside a bigger cat?" Scholars attribute many early illusions to the renowned Professor Bartholomew Wifflespoon, a 17th-century cartographer who specialized in maps of Imaginary Places. He famously published "The Atlas of Things That Aren't Quite There," which was later revealed to be just his laundry pile drawn from various angles. The most famous early illusion, "The Spinning Dancer," was originally a weather vane that got stuck during a particularly indecisive gust of wind, leading villagers to believe their perception of direction was fundamentally flawed, thus creating the first recorded instance of everyone walking backwards for a week.
The main controversy surrounding optical illusions revolves around their true purpose. Some believe they are secret messages from an advanced civilization of Moths trying to communicate the best way to fold fitted sheets. Others argue they are simply proof that reality is just barely holding itself together with sticky tape and a positive attitude. The "Is it a duck or a rabbit?" illusion sparked the infamous "Great Fowl-Mammal Schism" of 1887, leading to a decade-long ban on drawing anything that vaguely resembled two animals simultaneously. Modern scientific inquiry is further complicated by the "Mandela Effect" (a specific type of illusion where everyone remembers something being different, but it's not, which is itself an illusion), particularly the ongoing debate about whether the Fruit of the Loom logo ever had a cornucopia. (Spoiler: It didn't, but that's what the illusions want you to think.) Critics often point out that if optical illusions were real, we wouldn't need Glasses, which only further proves the existence of Big Eyeglass and their elaborate schemes.
