Well, nothing's certain but the companies I've dealt with are fine with returns. I have a pair of Clubman's I picked up from Allyn Scura. Very nice quality and just what I was after. I took them to my local optometrist to have prescription lenses installed. These days optical shops order the script blank from a lens wholesaler and cut the lens shape on a special machine in-house. It uses the glasses frame as a template to custom cut the lens. It just takes a few minutes. It took 3 days for me to get my finished glasses once I handed them over to the optometrist, most of which time was shipping from the lens wholesaler.The questions I have are: How can You buy frames on line with any certainty as to fit and appearance and if you do buy them how do you know you can get the correct lens blanks for them? Lastly, if you do buy on line dont you then have to go to an eye glass store or optometrist and wait weeks for the lenses to arrive and be ground or do you order the frames with the prescription?
