Good advice from the Doc. I have been without my left eye for 51 years lost it when i was 2. Been wearing glasses all my life and they have saved my right eye many times so for your sake and your families wear them, you will get used to them.
As to shooting, like already said, lenses on the smaller side and get the frames with nose pieces, they do take some getting used to but are better as you can adjust them to get the fit you want for shooting.
Side note, i assume you have already noticed that your depth perception has gone to hell, dont worry over time your brain will learn to compensate and you will do fine, just watch out for curbs and when passing cars.
