Aquasphere, the Italian brand of swimming and triathlon equipment, has released an interactive guide to lenses for swimmers. Available in five languages on Aquasphere’s website, A Lens For Every Condition pairs its 12 lens options with kinds of weather: sunshine brightness, cloudiness, precipitation, indoor conditions and so forth. The brand’s sponsored athletes, among them Tim O’Donnell and Mirinda “Rinny” Carfrae, offer tips, as well. All the packaging is emblazoned with a QR code that will forward users to the website through their mobile devices.
