While your at it, look into the transitional lenses. They act as sunglasses and regular glasses in one. The only thing I don't like about them is they will not darken in your vehicle (unless you have sun roof).
If you are a member of Costco, they have very good Dr's and excellent quality. You will not find a better price either.
I am in the same boat as you. Good luck and get your glasses asap.
