I believe that the concept of how the eye works was explored a few
decades ago. I remember reading something on it in some conceptual
papers about machine vision in the early 80's or late 70's. But the
technology of the time couldn't make much use of it. Also I believe
that this was machine vision equivalent to human vision, not as
described here.
But I wonder about eye-strain. I have worked in an environment where
lenses distorted the peripheral field and I got extreme headaches from
using it. And today I have glaucoma, which mucks up lots of areas of
your vision, requiring you to move your focal point and your brain to
interpolate what you see to extract the lines and intelligence out of
it.
I have a similar problem with my hearing where I lost much of the high
frequency spectrum, so my brain is working overtime just to make sense
of the world. My hearing was so bad that when I started using hearing
aids I practically had to begin to learn to listen to people all over
again. I still don't recognize some words well.
This is related because if you think of the bandpass of hearing as
similar to the foveal vision discussed, the higher frequencies are like
the peripheral vision of hearing. Missing frequency components (which
is more or less what is being discussed) removes some areas of
recognition.
While it is probably worth studying, I would bet it lacks sufficient
consumer benefit due to the stress factors and other issues that would
lead to customer dissatisfaction.
