I bought these for driving, but I'm selling them because I don't use them much anymore. These are clip-on sunglasses (front-mounted sunglasses) that can be attached to your everyday glasses with a single touch. They are a standard model made by Nagoya Gankyo, with the "KEEPER" logo on the lenses. You can quickly flip them down when needed and flip them up in tunnels or indoors, making them very convenient for driving and fishing. 【Product Details】 ・Brand: KEEPER (Nagoya Gankyo) ・Type: Clip-on / Flip-up ・Lens Color: Smoke / Gray ・Functions: Polarized lenses (reduce glare from roads and water surfaces), UV protection ・Attachment Method: Simply clip onto the bridge of your glasses 【Size】 Actual size: (※Please measure and write the width and height of your lenses.
