Mind-blowing Video Reveals Why Your Brain ‘Blinds’ You For 2 Hours Every Day
The reason why your brain “blinds” you for two hours every day is explained in this incredible video.
The video explains how the brain is responsible for “constructing your reality” and how much of your eyesight is truly out of focus.
Kurzgesagt posted a video to YouTube called “In a Nutshell,” which describes how your mind perceives the outside world.
The clip explained, “You’re not living in this very moment that you are experiencing and nothing is like it seems. It turns out your brain constructs your reality as you are experiencing it, it edits your memories as they happen, it lives in totally different time spheres and tells you a story about the world that feels real.”
We only see a “thumbnail sized area” of our visual field in high quality, with the remainder being out of focus, the channel claims.
As a result, our brains must put together the remaining information, and they have a fairly clever mechanism for doing so.
The video continued: “Each second your eyes make three to four sudden jerky movements, saccades, of 50 milliseconds, focusing from one point to another.”
“Scanning your environment to get different sharp images that your brain then edits together.”
“During a saccade your brain shuts down your vision so you don’t see a wild motion blur.”
“This means that each day, for around 2 hours, you’re completely blind.”
The channel went on to say, “Instead your brain fills this time with its best guesses of what happened during the blackness. But it does way more – it turns out that you’re not really experiencing time correctly.”
The YouTube channel said, “Your brain takes a moment to process and then invents a reality, a present moment that’s not real.”
“What you feel is ‘now’ is in fact a selectively edited version of the past.”
Video viewers responded to the information by posting their thoughts in the YouTube comment section.
One user wrote: “Ngl I find this quite comforting. I think that the idea of my conscious self being just one part of an interconnected being, that has other parts that work constantly to support the whole makes me feel less lonely. It’s nice to think of one’s brain as a friend that has been there for you and helps you the best it can your whole life.”
And another added, “I like that I can now say I’m in the past, present, and future whenever someone says I got to live in the now. Got’em!”
