Right Before My Eyes"I'll believe it when I see it:" is one of the many common slogans included in our everyday lingo. A person who declares this affirms that he will not be deceived by another's assumptions or perceptions of the world. This understanding arouses in us a great sense of security regarding the things we see and, conversely, an inevitable sense of insecurity in those beliefs that are not supported by vision. Do you believe in ghosts? Angels? Out-of-body experiences? Would you believe it if you could see them? Maybe not. But it is possible to offer deniers the stamp of approval on things that exist but are not seen, a better summary of the evidence, which might make the inability to see something an invalid criterion of belief. Could a summary of the evidence be compiled to support this: Is our vision incomplete, incorrect, and may even be misleading to the point of creating something in the brain that doesn't exist at all, shedding light on a brain that is more visionary? , and fewer reporters. Humans rarely contemplate the significance of their blind spot, a place where the processes of neurons come together and form the optic nerve; this is where the brain receives no input from the eye about this particular part of the world. What I discovered while having fun with a simple eye exam aimed at revealing the brain's capabilities when dealing with the blind corners of the eyes was fundamental in my exploration of the trust we place in sight, and so I will explain it to you briefly. Our brain can ignore a dot on the page and "fill" the dot with the color of the surrounding environment, regardless of color. However, it's not that our brain can't conceive an image or shape to fill this place. As you continue the experiment you will find that the brain will continue the line obstructed by the black dot, covering the sides of the dot with the surrounding color and transforming the image in front of you into a line inside your brain. A line that is absolutely not there. This reveals more than a weakness of the eye, but a skill of the brain! (1)
