I am an appellate attorney, which means I spend my days reading records. My eyes had gotten to the point that I really couldnt read small print and looking at a computer screen was impossible. I tried so many products and then found these glasses. I swear, but for these glasses, I dont think I would have been able to continue in my chosen field. I still have the first pair I bought in 2017. They are fabulous and sturdy and I thank goodness for them. I own several pairs now so that I have a pair at home, in my purse, at my office and in my computer bag. I never want to be without them!!!Suzanne
