Interesting tidbit on human vision

I am getting ready to do a video on resolution as it pertains to riflescopes and I stumbled onto this nice tidbit from quora:

https://www.quora.com/What-is-the-resolution-of-the-human-eye-in-megapixels

While I think of a good way to explain this, consider a concept of “acuity vs superacuity”.  It is directly relevant to observation devices and riflescopes.  Human eye acuity is roughly equivalent  to 3000×3000 pixels seen on a 19″ screen, two feet from your eye, while superacuity bumps it up to 18000×18000.

Let that sink in, while I plan a video on the subject.
