This is interesting. There are definitely some differences in the way the human eye sees Vs. how a digital component "sees". As a photographer, one question I get a lot is usually, "Are digital cameras anywhere near the resolution of the human eye yet?"
Well, that's a loaded question, because humans use their peripheral vision very little when compared to the center portion of their vision, which is where all the attention goes. If you look at how the human retina is put together, you see most of your rods and cones concentrated in the middle, getting more and more sparse as you go further out. A digital sensor - thus far - concentrates on 100% of it's surface area. So it's not a fair comparison.
I'm interested, also, in the ability to use contact lenses as cameras so as to get the best first-person view of what someone else sees. However, I understand that the jerky movements of the human eye make it a terrible option as a camera.
