It sucks to get old and loose that wonderful vision we used to have!
My solution... was to mount a pistol scope (they have a long eye relief) on to my bow. The scope I use has a range of 2 to 7 power but I leave it set on the lowest power. I don't need any magnification, what I needed was a clear picture of the target with a crosshair to aim with. I have it zeroed at 25 yards and would have to hold over for longer distances, so I try to keep my shots within that distance. Give it some thought, It worked for me. Good luck out there. BOBinIN
