Rehabilitation / Re: Monocular Double Vision & Astigmatism--Connection?

after about 3 weeks of taking into account in my plus lenses the right/left eyes refractive state ratio, I feel my vision is more stable at far distance and a little sharper. Although I will measure left and right visual acuity in few months and that will be a more objective review.
I now feel while print pushing that also my weaker eye does active focus and with both open they cooperate better. And not just feel but testing and closing my dominant eye while I'm at the medium blur zone while print pushing. Then I see that my weaker eye is at this zone and not at the blur zone that cannot make out the letters as I was before.
Even with my weaker eye wearing a lower plus lens, it continues to sees just a little worse than my left stronger and I knew this would happen when doing my Snellen test before buying the lens. If I marked that my difference was 0.75D and not 0.5D that I had many chances to change my dominant eye and messing around. I didn't want that to happen.
I'm so happy with those first signs of improvement that I'll take the nest step and start wearing myopic glasses again after many months just for a few hours per day while watching the subtitles on the tv at far distance (print pulling I think is named in this forum). So I will buy 0D for my good left and -0.5D for my right eye with diplopia. (Even my good eye has much room for improvement because I only see 20/20 line on a sunny day).
And yes, taking the "equivalence function" in diopters instead of cylinders with the suggestion that Mr Brown and others gave us is very satisfactory.
I'm glad you are an active member of this forum chris and I'm willing to report my results and hear from others like you about this very hard problem of dealing with diplopia after years of eye rehab. I also continue to do my active focus as an exercise with a Snellen chart and my astigmatic wheel exercise mod. I can clear diplopia for a few minutes in the 2nd exercise but the result doesn't lock in.
Before buying my new lens I did the Snellen chart not at 6m but at 3m in order to be more accurate about the L/R visual acuity ratio, because at 6m my vision fluctuates a bit and I thing at 3m we can be more accurate to a degree of 0.25D difference.
Small children that deal with amblyopia are made by doctors to patch for some time. So I definitely think that >=0.5diopters or 1 cylinder difference can stop the progress of even the good dominant eye in order not to result in amblyopia.
One other notice I've made at the astigmatic wheel is that a line that I can see without diplopia with my good eye and see it double with my bad then if I look the same line with both my eyes the brain doesn't just cancel out the diplopia from my bad eye but there is some diplopia also in the fused image.
