Notes:

When very fine spatial details are sampled by the cone array, the resulting pattern of neural activity can misrepresent the original object as illustrated in this example.

Notice how the finer stripes in the animal's coat are transformed by into an irregular, splotchy pattern that are a false representation. It is as if we've turned a zebra into a leopard! This mis-representation is called "aliasing" and it is caused by insufficient density of neural sampling elements in the retina.

Normally we do not experience aliasing in our central vision because the eye's imprefections prevents the really fine patterns from reaching the retina where they might be undersampled. In other words, one of the good things about having mediocre optical quality eyes is that we are protected from this false perception of aliasing. But if we improve the optical quality of the eye, we will have overcome the natural protection against aliasing that our eye's optical system provides.

So, in the end, improving the eye's optical system may not necessarily improve our visual resolution beyond the normal 20/20 or 20/15 level. However, vision may still benefit in other ways, such as improved sensitivity to contrast or flicker. At this point we don't know if the net gain will be worth the effort or not, but this much is certain: by correcting the eye's optical system to perform better than nature has intended we will be bravely going where no man has gone before, and the journey should be quite an adventure.
