Questions about simulating the human eye with regards to lens flare

[loccdor]

1) Would the "milkiness", veiling flare and low contrast of an uncoated 1920s lens, or the clinical high contrast of a newer Fuji lens, more closely approximate the human eye?

2) What role do our eyelashes play and what would happen if you attached a step-up filter with a bunch of glued-on strings arranged like our eyelashes are? I think if the eyes are almost closed the lashes almost take the role of a cross-screen filter.

3) The eyelid and squinting are like an aperture, but it's a horizontal rather than circular aperture. The iris is a circular aperture. Both of these work together. Or is it better to think of the eyelid as a hood which sometimes vignettes?

Cataracts, common as we age, cause glare as it clouds the eye lenses and scatters light.

My eye doctor, who understands photography, once told me that as my cataracts grew my lenses were being converted to pinholes, and that was the only reason I could still focus on anything. That got my attention and we scheduled the cataract surgery.
