Optical illusions are captivating the internet, offering a stimulating mental workout and a fantastic way to assess your observational abilities and visual acuity. Plus, they’re an enjoyable pastime! An optical illusion arises when our brain misinterprets what our eyes perceive. This happens when the information our eyes send conflicts with the brain's processing. These illusions can trick us into seeing things that aren't there or perceiving objects differently from reality. For instance, a static image might appear to move, or two identical shapes might seem to be different sizes.

The image features the word "pens" repeated numerous times. The words are prominently displayed in white against a black background. However, there's a subtle challenge. Hidden among the "pens," there's a different word. If you concentrate, you might spot it, but there's a catch: you only have 10 seconds! Get ready, set, go!
Did you give up? The hidden word is "pan". Due to the similar spelling, it's easy to miss. We've highlighted it for you below. Were you able to find it? Share your experience in the comments!
There are three primary categories of optical illusions:
Literal Illusions: These occur when the brain assembles elements of an image to create something nonexistent. For example, an image that appears to be two faces or a vase, depending on your perspective.
Physiological Illusions: These result from overstimulation of the visual system, such as excessive exposure to light, movement, or color. They can produce afterimages or motion illusions.
Cognitive Illusions: These depend on the brain's subconscious interpretation of information. Examples include the Müller-Lyer illusion, where lines seem longer or shorter due to the shapes surrounding them.
