"I was little hesitant to try on-line lense replacement but gave lenses ex.com a try based on reviews I read and I was not disappointed. I sent in 3 frames with single lense prescription and they were sent back in no time. However, there was a prescription error and the customer service was very helpful. I sent them back the frames and they came back corrected in no time and now they fit perfectly well. I would now buy with confidence from them anything including frames without paying three times to the other much known retailers."
