Well, that does sound binary, I admit. But we perceive things an an analog way, don't we? The light intensity governs the rate at which the cells fire, however, and that would be an analog quantity, I think.
In a truly digital system, the rate of firing would be assigned a number, which would be the digital representation.

As digital cameras have ccd's with a number of photosites (which determine the "megapixel" count of the camera, not the image quality), the human eye has a set number of photo receptor cells. Approximately 160 million rods which respond to 3 different wavelengths of light and convert it to an electrical signal which is sent to the brain. 160 million / 3 = 53.33 million. So approximately 53 Mega pixels. That does not necessarily mean the image quality is going to be good though.
