The original curved lens goggle. Following the successful launch of the Seal swim mask, Aqua Sphere applied its patented curved lens technology to a swim goggle, for the first time bringing 180-degree vision to traditional swim goggles. In addition, the Aqua Sphere Kaiman Lady swimming goggle changed the definition of comfort for swim goggles by introducing its proprietary Softeril material and easy-adjust side buckles, ensuring a perfect fit.
