I've purchased several pairs of glasses from this vendor. The first time was a pair of single-vision computer glasses. No problems. The second time was a pair of progressive lens. The frames were disappointing, but that's a hazard when buying from a picture on a website. The third time I decided to order the frames with the idea that I could return them to have lens put in afterwards. So much run-around I gave up and just ordered a new pair with progressive lens. The glasses came, but then I noticed that they weren't properly ground. The focal point was much too high, requiring me to peer through the top of the lenses instead of straight through the middle of the lens. I complained--run-around. "Send me your prescription", as if that had anything to do with an improperly profiled lens.
Apparently it's true--you get what you pay for.
If you just need cheap glasses for a simple prescription, I think they will do fine, but if there is a problem, don't expect much. They ain't Apple. For more complex prescriptions try Lenscrafters or some other brick and mortar place where they will insure your satisfaction before charging your credit card.
