The article “DON’T BELIEVE YOUR EYES? HOW OPTICAL ILLUSIONS WORK” explains how optical illusions occur when the brain misinterprets visual information. It describes four common illusions:
- The Hermann Grid: Black boxes with white lines create grey spots at intersections due to the retina’s light receptors processing light and dark values simultaneously.
- The Jastrow Illusion: Two identical arches appear different in size because the brain misinterprets the size difference between their long and short sides.
- The Penrose Stairs: A two-dimensional staircase that appears to form a continuous loop, caused by perspective distortion.
- The Leaning Tower Illusion: Identical photos of the Leaning Tower of Pisa appear to have different tilts because the brain incorrectly perceives them as diverging.
The article also emphasizes the importance of regular eye exams to ensure vision health.
