I'm about to give up on using the irons on my 995, even though others swear by them. I'm 57, severely nearsighted (in the double digit diopters), and squinting to see what's downrange. I just got an eye exam, and -- while my prescription has changed a small amount -- I'm not using lenses that are way off the mark. I _think_ I need some magnification or other clarification, but what do you suggest? How much magnification do you recommend, if any? Or (my ignorance shows here) are there some other non-magnifying optical options that I should be aware of. What scopes -- or other -- do you recommend?
