An optical illusion due to the physiologist Ewald Hering (1861). The two horizontal lines are both straight, but they look as if they were bowed outwards. The distortion is produced by the lined pattern on the background, that simulates a perspective design, and creates a false impression of depth. Discovered in the 19th century by German physiologist Ewald Hering, it's a veritable classic now. In the Hering Illusion two straight lines run in parallel. However, the intersecting radial lines change the appearance of these parallel, straight lines. What occurs in your visual system that could account for the illusory appearance these lines?
