how do i correct the eyepiece in the xtr that i'm using to account for the -8.75 prescription in my right eye? please, no suggestions regarding contact lenses, i'm 34 and have worn glasses for 30 years, so believe me, i've tried contacts already. i just want to know whether i can fit an external diopter to the eyepiece, or whether i need to adjust the eyepiece itself.
