Lehar Movement

Lehar movement refers to the visual phenomenon where a pattern appears to shift or move as you focus on it, but in reality remains static. It occurs because the brain interprets repetitive patterns differently at varying distances or focal points, causing a sensation of motion. Essentially, it's a trick of perception: when your eyes and brain process repeating images with slight variations, they create an illusion of movement despite no actual movement happening. This effect highlights how our visual system constructs our experience of motion and stability from what it perceives in static images.
