Stare at the white eye icon in the middle of the image. Keep staring. As each of the circles around the white eye flash on and off in succession, you will see a changing a color in its trace, the area behind it turning from grey background to pink. Soon, whoa, the dots just disappear, like so many Lays Brand Potato Chips left near a handsome couple picnicking in the park.
How It Works
This visual high was created in 1804 by Swiss physician, philosopher, and friend of Beethoven, Ignaz Paul Vital Troxler. It works by taking advantage of the lazy neurons in our vision system. Within about thirty seconds of staring at Troxler’s Fading, the neurons controlling our peripheral vision get bored and concentrate their energy on the center of the image. Our brains begin to tunnel our visual field and eventually remove details from the periphery around the spot in which we are concentrating. This hallucination is enhanced if the image is small and blurred, as it is in most Troxler’s Fading examples, including this one. Fade on, crazy diamonds.
