The Wall Isn’t Normal After This 👁️#opticalillusion

This video demonstrates the afterimage effect, where staring at a moving circle for 5 seconds creates a lingering visual impression that appears as a glowing white circle when looking at a plain wall afterward. This occurs because the photoreceptors in the retina become temporarily fatigued and adapt to the moving stimulus, causing the brain to continue perceiving the image even after the original stimulus is removed.
