Each of our eyes has a region (where the optic nerve enters the eye) in which there are no visual receptors. When you moved your face towards the screen you were adjusting your field of vision and consequently, the place on your eye where the circle's image was hitting. When that image was positioned where the receptors couldn't perceive it the circle disappeared! Believe it or not, this is happening to you continuously, day in and day out! Most of the time we don't notice these blind spots because we are using both eyes (they cover for each other) and we are constantly sweeping our field of vision so the blind spots don't last for very long. But they exist!
What's particularly interesting though, is that in daily life we don't notice the fact we have these blind spots! In the experiment, when the spot disappeared from your field of vision you didn't notice a gaping hole, a black void or a big question mark. What you saw instead was a continuous red field. This is a lie that the brain is actually creating, since the eye isn't actually telling the brain anything at all about that particular part of your field of vision. The brain simply "fills in" the most probable stimulus (in this case, a red area) where there is none.
Everyone has "blind spots" in areas of their lives beyond the visual. It could be around leadership style, perception of
what is "true" in their organization, or their sense of how they relate to others. These blind spots can be just as tricky to
perceive as the one you uncovered in the experiment. The point is, they do exist. They affect people's lives of a
daily basis and most people aren't aware of them. In fact, their brains may be making something up to cover for them!
