Great frame but I had some prescription issues from my optometrist leading to imperfect vision with progressive lenses. Eyebuy direct has been absolutely stellar and has been wonderful in rectifying my problem created by my eye doctor. I have nothing but praise for the people at Eyebuy direct. I will be a loyal customer for years to come.
