My new ones are from vision express.
Oakly Varifocal transitions thin and light scratch resistant anti reflection.
Not cheap but as I wear them constantly they need to be good and comfortable.
I had the first set with a more curved wrap around lens shape and they were horribly distorted around the edge.
No problem. They just sent then back no questions and I went for a different model.
These are lovely to wear.
I popped in after a couple of weeks to get the fit adjusted a touch which they did there and then. They also said to keep going in until I am 100% happy, no problem at all.
Far from cheap but they are high spec …err…. specs and I would not have got this level of service online.
I will stick to high street for my specific needs.
