The VC580 SWIPE corrective lenses are versatile corrective lenses that can be combined with the VPS570A Parts Kit to customize a pair of corrective goggles. With just two lenses and one VPS570A strap kit, the swimmer has a customized pair of SWIPE Anti-Fog goggles and a whole new vision underwater. SWIPE ANTI-FOG can clean the lens by a few finger swipes and clear vision will be restored. Please note: if purchasing the VPS570A parts kit, two lenses are required to complete the goggle.
