Positives: Very affordable, good frame selection with some frames clearance-priced even cheaper. Staff is friendly and helpful though not very experienced.
Cons: Any specialized request will incur an upcharge, including (in my case) a request to polish the lens edges, usually a standard practice. I have a high-minus (thick) prescription and requested that the lens be mounted in the frame such that the thick lens is mostly behind the frame as opposed to in front of the frame (an industry standard if not a simple request that I've made elsewhere for decades) only to have the manager tell me that this was not possible (?!) at America's Best. Use this business for your emergency pair of glasses or other un-critical eyeglass needs.
