This illusion is proof that everyone is unique.
Upon focusing on the spinning image, individuals will perceive distinct colors. While some might see yellow, others may see green, and a few might even see red.
The optic wheel is known as Benham’s top, named after the famous Victorian toymaker from Essex, England, Charles Benham.
In 1895, Benham designed the moving pattern intended for a spinning top.
Researchers remain uncertain regarding the reasons for the varied color perceptions among individuals.
One theory proposes that this variation is linked to the receptors in a person’s retina and how different individuals respond to red, blue, and green light.
As stated by Washington University: ‘It is possible that the colors observed in spinning Benham disks result from shifts occurring in the retina and other components of the visual system.’
‘For instance, the spinning disks may cause neighboring areas of the retina to be activated differently. In simpler terms, the disk’s black and white regions stimulate various sections of the retina.’
