I recently purchased a pair of glasses from glassesshop.com. They arrived with one lens incorrect - their "bad", I input the Rx correctly, they made it wrong. After having to waste more time than I felt I should to prove to glassesshop that THEY messed up, they did remake the glasses. The frames on these are so bent that the optical place I took them to for adjustment couldn't do anything. This has just become a comedy of errors! Now I have to switch the correct lens into the straight frame.
I buy glasses online frequently. In fact I purchased two other pairs of glasses from two other online businesses at the same time. Those had no problems. Glassesshop had the best price and the speed/shipping wasn't something I could complain about. But they need to figure out what Quality Control is. It would save a lot of people wasting time for things that should not be issues.
