“First, those horizontal lines are actually straight. Then, the ‘café wall’ illusion is one of the oldest known. Learn why the lines are parallel and why you see them slanted,” wrote Massimo while sharing the optical illusion on Twitter. The image shows several horizontal and vertical lines. Although the vertical ones appear straight, the horizontal lines give the illusion of bending at an angle. However, that is not true. In reality, these lines are parallel and devoid of any actual curvature.
An explanation of the optical illusion reads, “Cafe wall optical illusion. Do the horizontal bars look like they bend and are at an angle? Look again, because they don’t bend. They are straight and in parallel rows. The alternating target patterns, rows and colours all combine to trick your brain.”
