Abstract: An innovative flooded mask allows seeing both in air and underwater, thus overcoming the drawbacks of commercially available masks. The underwater telescope scheme is applied to a new flooded scuba mask obtaining correct eyesight in both underwater and above-water conditions. Optical design analyses and a test campaign on a sample of free divers have demonstrated that the mask is able to provide a wellcorrected vision in both conditions. Three prototypes, with increasing optical performances, have been optically and mechanically optimized and then ealized.
