SWANS Sports Glasses SPB-0051 BK Polarized Smoke Sunglasses Polarized Sunglasses UV Cut, Polarized Lenses Visible Light Transmission: 27% Ultraviolet Light Transmission: Less than 0.1% Comes with box, case, and instruction manual. The "SPRINGBOK" model, with a sizing that best fits modern Japanese people, and a sleek design that can be used by both men and women. The lenses are interchangeable, and the opening/closing parts are perfectly integrated with the frame design, without disrupting the overall form. Designed with ball sports (golf, baseball, tennis, etc.) in mind, it features a "structure and design that minimizes light intrusion." The nose pads use large rubber that is soft to the touch and prevents slippage even when sweating. The metal core inside allows for a wide range of and precise adjustments. It ensures the vision athletes seek and maximizes their performance. These are full-spec sports glasses recognized by professionals. Since I haven't used them, I'm selling them at a low price. #Sunglasses #PolarizedSunglasses #SWANS #SWANSsunglasses #SWANSpolarizedSunglasses
