Dave, when you shoot wearing glasses you are looking through the upper inside corner of the lens. that is not the optical center of the lens and some distortion of the image will happen. You can have your optician make you a lens for your master eye with the optical center high and inside. With that change, looking straight ahead will not be exactly perfect but way better than no glasses. My brother is an optometrist and made me a pair of dedicated hunting glasses like this. They work.
