Our brains can be easily influenced by how they judge brightness and color.
Roshni Patel, Optometrist and Head of Professional Services at Lenstore said this type of optical illusion can fool people.
“We have cells in our retina, one called cones which judge color and the other rods which judge brightness," he said.
"They then pass information through signals via the optic nerve to the brain, where it then tries to figure out what we are seeing by what signals it receives.
"Certain exposure to brightness, patterns, and colors can impact perceptions and that is what occurs when we see this color saturation optical illusion.”
