I’ve had my high-end RIA sunglasses for over two years. I am quite pleased. I only use them for Tennis. I keep them in the excellent case that came. I use the soft cloth to clean them. And they get a lot of wear. I play tennis four days a week minimum for an hour and a half in the hot Florida sun .Last month my original nosepiece basically broke. It came apart at Aw, aw a seam which is a little thin, but makes it nice and flexible on my nose. I tried to glue it back together that did not work. Therefore ordered two new ones from the company.I though the price was very reasonable at $10 apiece. They came within 3 to 5 days , they pop in easy and I am back to playing with my RIA’s.
