“This video will show you how amazing your eyes are,” the poster began.
The instructions are simple: look at the white dot in the center of the photo negative for 20 seconds.
“We are trying to adjust the sensitivity of the light receptors in your eyes to the different colors in the image,” the poster says.
When the original black and white reappears, your brain briefly perceives the full color image. How did that happen?
The effect depends on the creation of an afterimage, a short-lived illusion that acts as a passing stamp on our field of vision.
During 20 seconds of concentration on a white point, the cones in your eyes that are responsible for interpreting colors become desensitized.
Vox reported that the eyes will run out of photopigments, which convert light rays into electrical impulses that the brain can calculate.
“Once the image is removed, the least depleted receptor cells, which were looking at the darkest part of the image and absorbing the least amount of light, spring into action in full force,” they wrote.
“Your visual system is flooded with its input and briefly interprets it as the negative of the original image, even when it’s not there.”
On TikTok, the scene explodes with color and a purple van can be seen parked outside a bush-lined park against a blue sky.
“The effect will probably wear off as soon as you take your eyes off the white dot,” the poster added.
The video has nearly two million likes from viewers and stunned fans.
