The Zöllner Illusion

The Zöllner Illusion is a visual phenomenon that tricks our perception by depicting parallel lines that appear to be slanted due to the presence of intersecting shorter lines. These shorter lines are placed at angles, creating the illusion that the longer lines are not truly parallel, but rather diverging or converging. Despite the longer lines being straight and parallel, the surrounding angled lines mislead our brains, causing a distortion in how we perceive their alignment. This illusion demonstrates how our visual system interprets cues, highlighting the complexities of human perception and the brain's processing of visual information.
