I purchased these glasses, but the prescription wasn't right, so I haven't used them. The warranty has expired, so I think you'll need to replace the lenses to use them. The glasses case has some scratches, so please consider it a bonus. I had these glasses cleaned today when I bought another pair. Also, the photos were taken on a wooden table. The following is a quote from the website: Lightweight glasses that blend with your face and naturally brighten your look. Made with β-titanium and PPSU (super engineering plastic), they are extremely thin and light. They feature nose pads that fit comfortably and prevent slippage, providing a light and comfortable fit. The transparent coloring and metal parts, like accessories, brighten your expression. These are a natural yet polished pair of glasses.
