When being refracted for rifle glasses... what focal distance should be used?

This is a general question, but there is also a specific problem: when competing in long range events my eyes get tired (the target and the reticle blur out).

Hoping anyone has some insight... Koshkin

Please explain what you mean.

An example:
When someone is refracted for iron sights they typically optimize the glasses for the distance to the front sight.
When I use a scope, I wear glasses that only correct for a very minor astigmatism, but this gives them some small positive diopter. Is this optimal?
Thanks

Eyepiece adjustment takes care of that. If you change glasses, you'll have to readjust eyepiece focus again.
