Right-handed, right eye dominant, +2.5 diopter reading correction for me. Been shooting with progressive lenses and I really have to crank my head back to get the front sight in focus. I'm past the double image thing and have had limited success with letting the sights be fuzzy.
Last week, I took my wife to an indoor range for her first -ever- firearms experience. 2 guns, 50 rounds each. She took an .38 S&W 642 with CT grips and I opted for an XDM 5.25 in 9mm. I think she may be hooked. That's another story.
Still using my progressives, the fibre optic front sight on the XDM was like magic. My 24/7 is just as accurate as the XDM, but I was putting groups together like I never have before. Based on that, I just ordered FO sights for my Taurus.
I'm still contemplating putting a reading strip on the left side of the right lens, but I'll see what happens with the FO sights first.
