Whenever I'm really tired (like I've been up all day), my eyesight flickers when I blink. Kind of like when the power acts up and the lights flicker in a room. But with whatever I'm looking at. What the hell is that? Is it my brain being tired, or my eyes being tired? Is there a name for this phenomenon? I'm 23 and have astigmatism treated with glasses. I just find it weird and am curious.
