I went to my Eye Dr. today to pick up my new glasses...... The right eye has window pane for distance and +2.25 for reading.... SO the eyepiece diopter that is the best for me is .... Zero? or +.5 ? No more guessing about my age... you were off by only a year......

The +2.00 for reading tells me your probably between 49 and 52. Your distance prescription will determine the corrective eyepiece needed for clear vision through the rangefinder. Can you tell me what your distance Rx is? If we put our heads together, we can figure this thing out.
