Is it normal to see a small black dot flash in the corner of my eye?
Please help! What does it mean when I see a small back dot flash in the corner of my eye of about a second or less?? It only happens when staring a computer screen for long periods e.g. when making vector graphics.
I don't have vision problems as far as I know. The last time something like this happened was when one eye was blurred for a day or two after a whole day of screens and reading. (This is a different eye this time)
