These are semi-transparent framed sports sunglasses. The wrap-around lenses are lightweight, making them recommended for outdoor sports. I purchased these for tennis, but I've decided to use something else, so I'm offering them to someone who can use them. ● Material: Frame = Plastic (Nylon) Lens = Plastic (Polycarbonate) ● Size (approx.): Width 14 x Height 3.8cm, Temple length 13cm ● Weight (approx.): 17g ● UV Protection Rate (approx.): 99.9% ● Visible Light Transmission (approx.): 50% ● Made in Japan ※ Since there is no case, it will be shipped in an alternative case. UV protection is something you should consider throughout the year. In fact, UV protection is necessary not only for the skin but also for the eyes. These sunglasses have a UV protection rate of approximately 99.9% for both UVA and UVB rays, so you can use them with peace of mind. They weigh only 17g, so they're so light you'll forget you're wearing them. Recommended for everyday use as well as for walking and leisure activities.
