The human eye is an analog receiver, not digital. Megapixels do not (truly) apply.
As digital cameras have CCDs 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. The eye has recently been measured to have a mind-blowing 576 megapixels, but the very small area that the eye actually focuses on is only about 8 megapixels.
