Abstract: A panoramic-view diving mask with self-sealing, non-glued, removable watertight lenses. The lenses are self-sealed by an assembly process in which a layer of elastic gasket medium is applied or attached to either one or both beveled contacting edges of the frontal and side lenses, with the non-contacting edges having a lip so as to provide an enhanced seal between the lens and the frame. The lenses are assembled by pressing an assembly ring against the frontal lens and side lens simultaneously, forcing compression against the elastic gasket medium at the contacting edges of the two lenses and securing both lenses to the mask frame. The result is a watertight seal, achieved without adhesives, at the contacting edges of the front and side lenses. This process reduces storage space, packaging size and transporting costs during mass production.

Abstract: A diving mask having hemispherically-shaped lenses mounted on a flexible gasket or portion and fitted to the contours of a user's face. Laser scanning or topographic mapping is used to determine the contours of the user's face. Edges of the hemispherically-shaped lenses are then shaped to fit the contours of the face. As a result, the spherical center of the lenses substantially coincides with the optical nodal point of the user's eyes, or the center of rotation of the eyes. This virtually eliminates the phenomenon of underwater magnification-distortion caused by the difference in refractive indices of water and air. The diving mask may also have hemispherically-shaped lenses mounted on a support portion. The support portion, in turn, is mounted on a flexible gasket of selected size. A secure seal is provided between the diving mask and a user's face by the flexible gasket. The diving mask may be provided with at least one purge valve.
