In the course of buying a gel documentation system, and considering the
various camera options that include differences in the resolution of the
camera, the most common being 768 by 494 pixels (and 8 bit greyscale), the
question came up: What is the resolution of the human eye? This is what
will finally limit the useful resolution (at the desired output
magnification). This would be determined by the number of light sensitive
cells per unit area of retina and the closest point you can hold an object
to your eyes, and still focus (which will vary with age).

Anybody have the number?

Please reply by email.
