Sports goggles. These do not have prescription lenses. I used them for about a month during the pollen season as a preventative measure. They are adjustable. I used them around the time I was in the middle grades of elementary school. There is no warranty or instructions, but I purchased them for about 20,000 yen at a local eyeglasses shop. I wrote my name on the case, so there are marks where I erased it. (See photos) Please send a message if you have any questions. #SoccerGoggles #Kids #Black
