I sent my frames to be fitted with my Rx and add a bi-focal component for reading and the returned product looks like something from the '70s, possibly 1870's. I can't use the glasses because there is so much distortion it is disorienting. I contacted customer service and they told me that they made what I ordered and that I should have chosen progressive lenses instead of bifocals. They offered a 25% discount to let them remake them. I have no faith that the re-do will yield good results. The lens is thick even though my Rx is weak and so is the reading glass portion of it.
You get what you pay for and if you want to throw $150 in the toilet Lensable is a good alternative and will save water too.
