ABSTRACT:
A diving mask includes an elongate arcuate frame having two rearward formed lateral sides, a strap adjustably connected to the frame, a substantially arc-shaped lens having a smooth mediate portion and two side portions and tightly coupled to a front face of the frame, and a facial skirt sealingly coupled to a rear face of the frame such that the diving mask provides a wider view to a diver and defines a more compact volume between the diver and the mask.
