My eyes are very sensitive to flashing lights - for example I'm always the first person to notice that a fluorescent tube is about to fail because I see it flickering when other people can't.
When I'm driving at night, I perceive LED rear lights on cars as being a series of unconnected dots when I scan my eyes quickly across the scene. Evidently, many, if not all, LEDs are actually flashing at a high rate which most people don't perceive.
It almost seems as though I have a higher "refresh rate" than most people. How unusual am I? What is the physiology of it?
EDIT: I suppose what I find most fascinating is that at times when I see a trail of flashes, the spacing between them is remarkably consistent. This implies to me that there is an incredibly accurate timing mechanism somewhere in my visual system that is taking "snapshots" with clockwork regularity - probably between 50 and 100 samples per second. I'd like an insight into this "clock" and why mine seems to be faster than anyone I've ever met.
This similar to what I perceive:
