Schulz-Hildebrandt, a biomedical optics engineer at Harvard Medical School, ran with his observation and developed an ...

This trippy image appears to be a pigment enigma. Puzzle lovers are straining their brains over this optical illusion, which reportedly fools the viewer into thinking that they have gone colorblind.

A biomedical optics engineer discovered a visual illusion where purple dots appear bluer in peripheral vision. This ...

How many purple dots do you see in the image above? Are they all the same hue? This new optical illusion, developed by ...

At first glance, this image may appear to be just a repetitive pattern of the word “Colour” written over and over again. The consistent font, uniform spacing, and monochrome background all work ...

So I've read in more than a few places that color doesn't exist outside our heads, it's just wavelengths of light. That our brains are the things that make color, same with sound (which is just ...

Perception researchers have long known about the structural and functional features that differentiate our central vision from our peripheral vision. The central (or foveal) region of our retinas are ...

A study of mice starts to unravel how the brain gets tricked by this kind of optical illusion, and it gives clues about how visual perception works. When you purchase through links on our site, we may ...
