Have had many eye exams in the last two years (ophthalmologist) due to something else. I'm all okay.
This may be hyperawareness but I've noticed in the dark (bed-time) when my eyes are closed and I look quickly to the side/strain a little bit with far gaze - I can make my blind spots ''flicker/flash'' breifly. Is this normal? It happens in both eyes simultaneously and doesn't occur without the above action.
