This is not just a parlour trick but a way to demonstrate how what we think is reality may not be correct.
Each of your eyes has a blank spot, where the optic nerve is attached…your brain fills those 2 blank spots in as best as it can based on several things. Remember, what is received at the back of your eye is actually upside down and it’s the brain’s job to flip it 180 degrees in order for you to function.
Based on the above demonstration, what other things do you think the brain is inadvertently “correcting” for us?
