The Ponzo Illusion

The Ponzo Illusion is a visual phenomenon where two lines of the same length appear to be different lengths due to the surrounding context. When placed over converging lines, like the rails of a train track, the upper line appears longer than the lower one, even though they are the same length. This illusion demonstrates how our brains interpret size and distance based on perspective cues, showing that our perception can be influenced by visual context rather than just the actual measurements. It highlights the complexities of human vision and how we interpret spatial information.
