No brand These are sunglasses with photochromic lenses. Since they are not visible light photochromic, the color hardly changes unless in direct sunlight. The frame is brown, and the lens color is more gray after changing. I used them as fashion glasses. They are light and have a cute shape. I will send them in a glasses case that I wasn't using. I have cleaned them with an alcohol wipe. I plan to temporarily suspend the listing after September 25th because I will be unable to ship for a while. If you have any plans, please purchase early. ＜Product Description＞ Product... Brown frame, non-prescription, 2-way lens, photochromic lens, clear glasses, sunglasses Color... Brown Size...
