To simulate your eye with the graph paper test you would need to put a zero distortion lens in front of the graph paper (to image the graph paper at infinity, like your retina). Then you would have great test. But, it is hard to find a substitute for the compact lens/retina/brain visual system that corrects for distortion over a large FOV.

Sorry, but I still don't get it. Why not take the graph paper as representative of the effective function of my cornea (which, though domed, and together with my lens, projects a flat image as approximately focused on my curved retina)? The path from cornea to retina, is a constant across all binocular evaluations, so not of interest. I'm also not terribly interested in how well my visual system corrects for distortions. That too is essentially a constant. I'm interested in whether a bin can provide a view that is imperceptibly different from what would be a naked-eye view, only magnified 8x prior to delivery to my eyes.
