If my eye exam is good for 2 years then how do I go about getting a new pair of glasses?

You can stop by and order a pair of glasses anytime.

If you have a copy your last exam. You can go in or call to set up an appointment . Take your last exam in on your appointment date and time, give them the exam . Then they will go from there. If they see fit to do a new exam. They will . But if they don't they will go off of the one you gave them. They will have you pick out a frame that you like. And have it shipped out along with the order for your new lenses. If you have a set already an need new frames take them in an see if they have a set of frames that you like an that will also fit your lenses.
