Optical Illusion

An optical illusion is a visual phenomenon where the perception of an image differs from its actual reality, creating an effect that tricks the brain into seeing something that is not there or seeing something differently than it truly is.

These illusions occur because the brain processes the visual information in a way that can be influenced by various factors such as light, color, contrast, perspective, or the layout of the image itself.

There are many types of optical illusions, ranging from static images, where the illusion is created through patterns or shapes, to dynamic illusions, where movement or changes over time play a role.

For example, some illusions cause us to see movement in still images, or make two objects of different sizes appear to be the same when they are not.

Optical illusions demonstrate the complexities of human visual perception and how our brains interpret sensory data, highlighting how easily our minds can be fooled by certain visual cues.
