I ordered glasses on September 6,2018. I received the glasses on September 28,2018. In the meantime, following an e-mail communication requested by them. I've wanted to cancel the order, but without success. The first thing I noticed when finally I got glasses was that the thickness of the lenses, I ordered (1.74 index) is rather (1.56 index) I had paid $220.00 more for a quality lens... and when I tried glasses I could not see anything with. I had, however, provided them a copy of my prescription from my optometrist. A week after informing the customer service of the problem, I am unanswered. I contacted Pay Pal regarding their guarantee. Optically finally answered that the thickness of the lenses can be different from one manufacturer to another. In the meantime, I observed that on the package of shipment that the product comes from a subcontractor "Plastic Plus" I'm communicating with them about optometry measures. A measurement in Optometry must be accurate and not random from one laboratory to another. Twice in four, I was fooled by the order online prescription glasses. I hope to have had my lesson! I also hope to benefit from the Pay Pal guarantee because it is with a Canadian company that the problem happened this time here!
