Resolution of the human eye?

Since the human eye doesn’t see in pixels at all, it’s pretty hard to compare them to a digital display.

But curious minds want to know, if you could compare the two, how many pixels would the human eye likely have? It turns out, someone smart used some pretty complex math and (assuming 20/20 vision) got to 576 megapixels. 576 megapixels is roughly 576,000,000 individual pixels, so at first glance, it would seem that we could see way more than an 8K TV has to offer. But it’s not that simple. For instance, we see in 576 megapixel definition when our eyes are moving, but a single glance would only be about 5-15 megapixels.

What’s more, your eyes naturally have a lot of flaws that a camera or digital screen don’t. For example, you have a built-in blind spot where your optic nerve meets up with your retina. You might also have a refractive error like nearsightedness or farsightedness. You might have also been born with (seemingly) super-powered eyes, like tetrachromats: people with four cone cells in their eyes instead of three. This means they can see many more colour varieties and therefore, when looking at a TV, could potentially distinguish much more than the average person.
