Ninio’s Extinction Illusion is a fascinating optical illusion where your brain “extinguishes” certain details, prioritizing what evolution decided was most important. It’s a vivid reminder that what we perceive isn’t always the full picture.

This version, a Hermann Grid variation, shows you that your mind will not let you see all 12 black dots at the same time despite the fact that the entire grid is in your peripheral view. It was popularized in 2000 by French scientist Jacques Ninio, and highlights the illusory nature of perception.

Ancient philosophers explored this concept deeply. In the East, they might call it Maya or the veil of illusion; in the West, they spoke of Plato’s cave or the shadow of appearances.

Our eyes may show us the world, but reality might just be playing tricks on us.
