I bought these at DisneySea because the sun was so strong, and I used them for about half a day. While they don't feel like a high-end eyewear brand, they did reduce the glare that made it difficult to keep my eyes open, and I was able to enjoy myself. I don't think I'll be going in the summer again, so I'm putting them up for sale. Color: Brown系 (Brown-toned) Stains, tears, odors, etc.: None
