A few minutes after I turned the light off, when my eyes should have adjusted to the dark, something didn't seem right with my vision. So I covered my left eye
with my hand, leaving my right eye
open, and everything went pitch black. I couldn't see anything out of my right eye. With my left eye I could see the shapes and shadows that you can usually make out in a dark room, but out of my right eye was just total pitch blackness.
