Actually, human eyes don't have a "frame rate" per se, or if you want there are different frame rates depending on the feature - and how far removed it is from the retina. Essentially, the retina itself can detect >300hz, then there's a bunch of processing as you go back the optic nerve that causes that number to drop for higher-level features.
