I wasn't sure where to post this, but biology seemed fitting for me. Sorry if I'm wrong.
I was wondering why, when we close both our eyes and look at light, it is clear we can see the light even though our eyes are closed. We can identify where the light is too.
However, when you look at the light with only one eye closed, suddenly you cannot perceive this anymore and you can only focus on the open eye's vision. It's like our brain is ignoring the closed eye's vision somehow. What is triggering this "ignore vision"? Is it the closing of the eye?
I found this intriguing and wondered how this works and/or if there is any research about it.
