I had two expensive designer frames that I needed progressive lens. I went to all of the major big box eye glass providers and was given outrageous prices. I would have to pay EXTRA because it's not their frames.
I was on Groupon and saw a sale on progressive lens by Lensabl. I took my pictures so they can match my sight lines up. Two weeks later I got my frames back and was just amazed lol. They were perfectly done.
I will use this service again and I highly recommend that you try them out.
