Eli5: what do we see when we close our eyes
In: 1
You see the inside of your eyelid and whatever light can get through that (very thin) layer of skin.
Your eyes adjust to the darkness, sensitizing to the low-light environment and trying to pass useful information to the brain. If there’s a sudden bright light, you might see it through your eyelids.
If you see colors or other artifacts, it’s the optical nerves trying to communicate *something* rather than *nothing* in an environment relatively devoid of information.
