I struggled with changing my form a bit to accomadate wearing glasses, but still could not get used to wearing them especially hunting during cold weather. This may not be an option for you, but I switched to contact lenses and it suites my shooting and hunting much better. Not all visual problems are correctable with contacts. I can actually see a little crisper with the glasses, but over-all function better with the contacts. Getting used to putting them in took some practice as well but it was worth it to me.
