What is the maximum angular resolution of the human eye?

How many pixels does the human eye have?

  • The binocular, central field of view is about 60 ∘ vertically and 120 ∘ laterally, so if you divided that up into the smallest cells it would be possible to resolve with human-sized pupils, you'd get about 112 million "pixels." Of course, human eyes don't work nearly that well, so this is just an upper limit.

How does the human eye work?

  • It is more like a video stream. The eye moves rapidly in small angular amounts and continually updates the image in one’s brain to “paint” the detail. We also have two eyes, and our brains combine the signals to increase the resolution further. We also typically move our eyes around the scene to gather more information.

What is the difference between acuity and resolution of vision?

  • But acuity is the measure of how much we can see in any one direction that the eye is pointed. According to this article, the maximum “resolution” we see with is about 180,000 cones per square millimeter. It tapers off as we get further away from the center.
