Purchased 2-pair transition, progressive w/bifocal glasses 02/29/2016 at the Northlake Centre Pkwy-Charlotte, NC location. $511. Glasses never improved my vision though sight was more 'crisp.' I tried to 'train my brain' to adjust to the new glasses for 17 days. Constant headaches. The progressive lens glasses/prescription simply didn't work for me for whatever reason. I returned the glasses and was refunded in full with no hassle; however, I lost confidence in America's Best and will have my eyes re-examined to obtain glasses elsewhere.
