I bought OLIVE 830 DKGUNM rimless glasses, gunmetal Deal £25 A day later I was called and advised to have polycarbonate lens, as they were rimless frames. I paid extra £25. I also said I may have ordered a frame too narrow for my face, advisor said measure existing rimless frame and they would make the new ones the same dimension. They did this. Great glasses, with all the coatings, as promised. I bought arms length vision glasses, so lens bit thicker than my standard vision lens, but not thick like a reading prescription. I am happy, and would buy from Perfect Glasses again. But they do not offer a fitting before buying. Guess you can't go wrong with rimless style anyway. Cheers Guys
