This is a listing for YAMAMOTO YW-390 two-lens shade glasses from Yamamoto Kogaku. High protective performance, featuring an eye cup frame. Polycarbonate hard coat with anti-fog treatment. Shade level #1.7 (see photo). The lenses are a bright green color. Made in Japan, JIS UV cut. The lenses have no prescription. I purchased these new as a replacement for lost outdoor sunglasses, but I found the sunglasses, so I am listing these. I have not used them outdoors. There is no dedicated case, so I will include a simple sunglasses case. Thank you.
