Human vision does not see in frames. It's a continuously integration of visual input where the brain is really good at finding anomaly.
For example. What you see is only integrated into your consciousness about 15 times a second. You may think that's 15fps, but it's not. The brain integrates many visual cues and adds meta-data to objects seen, like direction of movement. If an object jumps more than a small percentage of its size, your brain will see the same object as two different objects. This means if a rocket goes flying across your screen, it can't move more than a few pixels at a time without confusing your brain into thinking there are multiple rockets.
In laboratory experiments, humans can see into the thousands of frames per second and can recognize a pulse of light as short as a few femto-seconds (0.000000000000001 seconds) in pitch-black aka 1,000,000,000,000,000 fps
FPS/HZ does not apply to human vision. We don't see in discrete amounts, we have a more analog vision.
