Lila Gatlin was writing about this in the 1960s and 70s.
"Life may be defined operationally as an information processing system—a structural hierarchy of functioning units—that has acquired through evolution the ability to store and process the information necessary for its own accurate reproduction." --Lila Gatlin, Information Theory and the Living System, 1971
I'd like more insight on how Adami's contributions are especially significant (which they may be, but TFA doesn't make that clear). Or is it just that he's a really good spokesman?
Since you're on
deltaA/deltaX = 2 × deltaM/deltaY
where A is the astigmatism created by the lens, M is the power of the correction provided by the lens, and X and Y are the usual coordinates. Thus progressive lenses always get blurry in direct proportion to the difference between your near and far correction, and in inverse proportion to the vertical distance between the near and far sweet spots.
In practice, some advanced techniques such as grinding both sides of the lens and applying wavefront or raytracing optical simulations can make the problem less noticeable (mainly by moving the worst areas from one spot to another). Some brands of lenses are better than others, and some labs do a better job of making them than others. If you go for progressive ("PAL") lenses, ask to see the "occupational" lenses from several different manufacturers. Learn how to see the "invisible" manufacturing codes printed on your lenses.
My solution at the moment: fixed-distance computer glasses, plus Hoya Summit iQ PAL lenses adjusted to increase the size of the reading zone a bit.
