One of the things that has really helped my shooting in the past few weeks is the realization that the glasses that I was using basically gave me 20/20 distance vision. The problem with that is that I was not able to keep focus on the front sight. I began testing a  week and a half ago with +1.5 diopter readers. That worked. I also ordered a set of sports glasses from Zenni Optical with the left lens for distance and the right for the hyperfocal distance of an AR (about 40 inches or so). With good eyesight (like I used to have) this would be +.75 diopter  with my current situation it is +1.5 diopter. I need .75 for distance and an additional .75 for hyperfocal for the front sight on a 20inch barrel.

With almost 2 weeks of testing I am shooting better than ever. It's funny how being able to REALLY focus on the front sight lets you shoot well. But front sight focus is not one of the fundementals of marksmanship for nothing.
