Well, as Vsauce explains in its latest video, the better question is actually: What is the resolution of the human eye?
It’s a complicated question, one that must take into account the peculiar anatomy of the eye which is different than the less peculiar engineering of a digital camera. As such, it’s worth watching all 10 minutes of the video, explaining not only how we see but also how well. Spoiler: the human eye is 576 megapixels — but really only about seven megapixels matter.
