. . . and mine 55, and myopic. But the diopter "peep" sight will make for quite a bit of distance correction with either hyperopia or myopia. The sight picture of the official 10-M competition target's black ring centered in the correct size aperture of the front globe, centered in the correct apparent size of the 1mm aperture of the rear sight (changed by adjusting the eye relief position of the diopter sight) in good light is a very high contrast sight picture and at least in theory, pretty easy to center. Your focus and concentration should be directed at the front sight globe. Targets like the Gamo 6.5 inch targets with a white center and black outer ring, BTW, are much harder for me to shoot accurately with diopters, while in silhouette, the white center of a Gamo target makes the black front blade of the Izzy easier for me to line up. I have actually added a fluorescent dot to the front blade of my Izzy to make centering the front blade against a black target easier for my tired old eyes. I shoot 10-Meter targets with my computer glasses both with my IZH-46A and my Walther LGR-U without too much problem, but again, a good light (I use a small, cheap halogen desk lamp) centered on the target will greatly improve your sight picture. The diopter sights will also put the line of sight much closer to the bore.
At least for me, a scope with any magnification seems to merely amplify my wobble, a pretty distracting visual effect, making it harder for me to truly concentrate on the sight picture, think about my breathing, and trigger pull. I shoot more consistent patterns at 10-M with diopters than I do, for example with my HW30S tuned to 575 FPS and a 2X scope, and I don't think it is the spring.
But, all that said, don't expect to then pick up the FZB with diopters and easily acquire a target tree rodent at 25 yards, much less a grasshopper. Although I must say the pictures of that big old scope hanging off that offset mount looks pretty *_*_*_*_*_*y, I am not sure it is optimal for printing targets at 10-M, at least for me. That said, I certainly am no expert on the subject, just a rookie trying to learn if I can really shoot a 10-M rifle. I seem to have a gnawing desire to acquire a really fine, new single pumper like the FZB 603, but my logic has prevailed so far, in that I have decided to refrain from any new shooters in the 2+ killobuck range until I can prove to myself that I can actually shoot my Walther well enough to deserve one -- that and the fact that such an acquisition will surely come to the immediate attention of my loving, practical, and frugal wife with potential consequences that need not be stated here.
