Optical illusions don't tell us much about our vision. Instead, these illusions give us insight into the way our brains interpret colors and images. After all, our brains decipher visuals; our eyes are just the messengers. Our brains may actually perceive colors based on how they compare to surrounding colors, not just from the color itself. The "flash lag illusion" reveals an interesting thing about our brain as well: that we're living ever so slightly in the past. Roughly 80 milliseconds in the past, that is, because it takes some time for our brains to perceive images.
