Costco has prescription glasses at a significantly lower price than other stores in town. Not a great selection of frames, but I found ones that work for me. Even though my prescription has been changing more lately (the Dr. says cataracts can do that) I splurged and got 4 pairs last month. Got two pairs of bifocals for outdoor activities, one polarized and one clear, with minimal reading area and two pairs of progressives, one that they called "multifunction" with a small distance area at the top like what Scoutergriz described and a large middle area for computer focus and the other pair more normal progressives with the top half for distance. With their $40 off each additional pair special the total was just under $500.
