How many mega-pixels does the human eye have?

Question

In what resolution does the human eye see?

Answer 1

The resolving power of the human eye is measured by how close together two points have to be before the eye fails to resolve them as separate points and they blur together.  And that depends on how densely packed the photo-sensitive cells in the fovea are.  The maximum resolution equates to 0.47mm at 1m. That's better than Hi-Def given a typical viewing distance, right?.

But the eye/brain also can make things merge.  It doesn't want you to see dots and pixels, so TV doesn't look that bad. It fills in the gaps.

Answer 2

"The human eye is roughly a 25-millimeter diameter sphere with a retina that contains about 120 million rods (black & white sensitive receptors) and about 6 million cones (color receptors). The region of greatest acuity is the foveola, which contains about 15'000 cones and is centered in the fovea...  today's rather ordinary 8 megapixel sensor cameras, which have something on the order of 3500 x 2500 pixels in their field of view. But the total "pixel" count of the human eye is about 126 megapixel, far beyond the 8-megapixel camera example."

Human eye: approx 126 megapixel

resolution: approx 11'224 x 11'224

remember that the retina is spherical, not square like a camera "retina"

I hope this helps
