I coughed and saw #phosphenes just now. I remember the first time that happened, I thought I was having a stroke.

I see points of light, usually blue-white and moving in straight lines vertically or horizontally a little ways before winking out. Sometimes they are like the absence of light instead of light. Sometimes they move in 45 degree angles instead of vertical or horizontal, and once they moved in squiggly lines instead of straight.

Pressure on the optic nerve, they say...
