I have just , with a great deal of trepidation, bought my varifocal glasses on line via specs-by-post & have been amazed by quality of service & goods. They cost 105 pounds as opposed to my last pair in France at just over 650 euros. I had my eyes tested on a trip to England & just sent this with an old pair to them & they are perfect. I may have been lucky but , hey, to save that sort of money it was worth the gamble.
