It’s common sense to assume that human vision is based almost entirely on human eyes themselves. However, it turns out that this isn’t the case at all. More specifically, the lens of the human eyeball focuses light back to the retina, where photoreceptive rods and cones are impacted by wavelengths of light. To put it another way, light enters the eye by way of the optic nerve, after which it is then interpreted by the human brain; raw data regarding light wavelengths is untangled, and memory is utilized to decipher the images which the brain eventually “sees.”
Indeed, there is much more to human vision than merely human eyes. As discussed, visual stimuli are processed in the brain, even when the stimuli cannot be 100% untangled. In these cases, the brain’s ability to draw the best conclusion possible based on the information and variables at hand—or pareidolia—is frequently utilized. In fact, this is a big part of the reason that human beings often see “faces” in clouds, bushes, and other natural forms. However, some people “see” these images much more frequently than other people, and some people never see any at all.
It takes an extremely perceptive individual to spot these sorts of things constantly. Or, to look at it another way, it requires an individual who has evolved beyond the first stage of pareidolia (detecting these things was essential for survival back when many predators actually did lurk in most bushes—while hunting humans). Do you think you’re in the upper echelon when it comes to perception and insight? If you think you’re up for the challenge—or if you’re just curious to find out if you might be—checkout the images below and decode-away (if you dare).
