Take a 30 Second Break And Check Out This Optical Illusion!
It’s an example of a phenomenon known as Troxler’s fading.
It was discovered by Swiss doctor Paul Troxler in 1804, who found that the brain stops paying attention to visual scenes that don’t change.
With the image being so blurry and indistinct, there is little for the eyes to focus on. And if you combine that with an intense stare, the colors fade from view.
