Human Eye

[Agent_sm1th]

What is the frame rate of the (normal) human eye? I would have thought it didnt have one but sometimes when you look at cars wheels they do seem to be rotating backwards (i do know why this occurs). Does it also have a resolution (my guess would be not but if it did, it would be interesting to know)

doesn't have a frame rate or resolution, it's analogue therefore infinite range within its parameters. it would be like saying how many points on a line, digitally a limited number depending on resolution, analogically, infinite.

Your "backwards" efect may be because you are looking at the wheels in artificial or street lights. Sodium or mercury vapour street lights have a definite 50 cycles per second flicker. Too fast to see, except at the very edge of vision, but capable of interfering with the vision of moving objects.

BLAST!!! No edit facility! BOTHER!!

That should be "effect"

DOUBLE BOTHER AGAIN!!!

ah but (microfish) that is not quite true - the signals from the eye are sent to the brain via nerves - electric impulses (in effect a digital signal) and therefore there must be some form of frame rate. Correct me if i'm wrong but you see the "strobe effect" (which is what we're talking about here) when looking directly at a propellor blade winding up on an aeroplane? in daylight? I am not precisely sure about the medical breakdown of the eye but these facts would point to it having a frame rate. opinions welcomed.
