SAN DIEGO, CALIF (November, 2018) - Of all the senses, sight seems to be the one we can rely on most. Seeing is believing, right? Not necessarily.
In reality, our sense of sight is a lot trickier than we might think. Oftentimes, what we think we see is actually an illusion that the brain creates to supplement images glimpsed in our peripheral vision. According to a study published in the journal Psychological Science, much of what we see in our peripheral vision is just the mind making up things that aren’t really there.
“It sounds a bit like The Matrix, but the line between reality and illusion gets a bit murky when it comes to how the brain processes visual input,” explains Sandy T. Feldman MD, Medical Director of Clearview Eye & Laser Medical Center in San Diego. “The study suggests that our peripheral vision is less detailed than what we see in the center of our visual field, but we don’t really notice any difference because our brain ‘fills in’ some of the missing pieces.”
Here’s how the experiments worked:
“Researchers hope to eventually understand why this phenomenon occurs. Perhaps because we don’t take in as much information from our side vision as we do from the center, the brain might be making an educated guess,” says Dr. Feldman. “So just because we see something with our own two eyes doesn’t always mean that it’s real.”
