Don't know the answer to that, but one qualifier I can add is that the megapixels would not be evenly spread out - there is much better definition in the central region of the eye than in the periphery.
You should find that it is roughly equivalent to 300dpi at reading distance (around 14 inches).(As an aside, it is beneficial to have 600 dpi laser-printers for text because sometimes you'll look at it more closely! Also you need higher resolution to do half-toning for good greyscale images.)
I would therefore be surprised if the human eye can actually resolve 300dpi at 14 inches.
horizontal resolution is actually very important for stereoscopic depth-estimation
That makes lot of sense. Is there any difference in the structure of the retina to enhance horiz resolution?
There's a zomeplate image (not as big as ideal, but hey it's a start) on my never-finished zoneplate webpage: http://techmind.org/zoneplate/ (use the "greyscale" zoneplate)
Human sight is an analog system, we cannot how many megapixels
Human sight is an analog system, we cannot how many megapixels does the human eye can get, we are not digital systems.
Anyway, I got round to printing out some black lines on a clear plastic sheet. They are about 0.6mm "wavelength" ie 0.3mm white, 0.3mm black. I will have to wait now until I get to see them in good daylight.

"What do I have to do? Supply you with a bitmap?"You might want to get your website to give anything other thah a 404 error
They eye is composed of discrete photoreceptor cells, which are finite in size. In this respect we have 'digital' vision.
