I wonder if someone can shed some light on a problem I had recently. Here's the background first. My father recently passed away, and I had to wait several days before I could go to the funeral (which was abroad). During those several days I hardly slept because I was very upset. On the day I was to fly I was extremely exhausted and my left eye was very tired. I remember looking at the lightbulb on my lamp (it was turned on) and suddenly seeing a flash of light that lingered for a long time. Then my left eye temporarily list vision.
My question is: is my temporary loss of vision because of my stressful situation?
