I can only wear pure titanium. When my old branded glasses fell apart, I searched the internet for alternatives. After reading great reviews on this product and researching the brand name, I was hooked. The price is cheaper than most sunglasses. When they arrived, I immediately appraised the material and construction. Mine are golden, beautiful and very light. When my optometrist saw them, he was pretty impressed too. He installs my prism lenses and I should have them in 3 weeks.1. These shots are really cheap2. I think the quality is excellent3. They're lightweight, which means they don't get heavy with my lens4. My optician can work with it5. They suit me pretty well. I even bought extra frames in case I damaged them. I recommend this product!
