I have purchased them for several years and had excellent service from Edgar Garcia at Elton Optics in Las Vegas. Web site at http://sunglasspolarized.net/

Does anyone know if Elton Optics still exists? I need to get a new pair of prescription sunglasses. I called Elton Optics and the call was answered by Eagle Eyes automated service.
I used to order his Avian 515 Non-Polarized Lens. They are great and the service was very good.
