When I ordered my varifocals through the site it didn't make it clear in advance that I would be required to either send an old pair of glasses in or upload a photo of me wearing glasses. This delayed the order that I had wanted in time for a holiday so they were waiting for me when I got back. The lenses are good, I'm pleased with them. The other thing I hadn't bargained for, is that they don't necessarily fit that well when they arrive as the arms haven't been shaped to fit. Mine are too straight so the glasses slip when I lean forward. I researched how to reshape them and tried the hot water/bending method but they still aren't quite right. All in all; for the saving I've made from high street prices they are acceptable, not sure I would actually use them again.
