I would think that the electical frequency in a florescent light would indeed produce a strobing effect, but I'm sure I recall seeing the phenomenon outside in pure sunlight.

I am very skeptical about a human vision update frequency, and would love to read about such evidence.

I think a lot of blurring that is being seen is related to "persistence of vision." This is what is responsible for movies looking like smooth action rather than discreet frames. Any image that hits the retina will retain for a moment.

I've seen this effect as a shadow that follows behind a dark moving vehicle when the background is light. Or more obvious: just staring at a light & then turning the room to pitch dark will produce an image that hangs around for a long time.

I'd be very surprised if "persistence of vision" has been "busted". That combined with the idea that there is a human vision frame rate would be a significant scientific revision & I'd like to see a paper on such.
