OZNIS lenses, a product of Talex, made in Japan. The color is Luster Brown. The lenses are mirror-type. They are very light and comfortable to wear, as expected from Talex. I used them a few times for fishing. I bought them new for 28,600 yen, but I'm selling them because I'm using a different pair of polarized glasses and haven't been using these. This color makes underwater structures clear. It enhances contrast, making the outlines of rod tips, lines, lures, and floats sharp. Visibility of what you want to see is improved.
