A diving mask with supplemental vertical, lateral and posterior fields of vision. A pair of sealed compartments at opposite ends of the diving mask have rotatable mirrorized surfaces which reflect light rays from objects above, below, or the side and rear of the mask into a diver's view. In a first aspect of the invention, the mirrorized surfaces are rotatable about vertical axes to provide supplementary lateral and posterior fields of vision in varying amounts. In a second aspect of the invention, the mirrorized surfaces are rotatable about horizontal axes to provide supplementary vertical and posterior fields of vision in varying amounts. In a third aspect of the invention, the mirrorized surfaces are on members which are rotatable with spherical joints to provide supplementary vertical, lateral and posterior fields of vision in varying amounts.
A diver's mask for enlarging a diver's field of vision, comprising:
In a diver's mask of the type having a front portion for receiving a lens, a transparent side portion adjoining said front portion, an interior for receiving a reflector and a seal extending around a perimeter of said mask for sealing said mask against a face of a diver, the improvement comprising a reflector mounted for rotation in said interior of said mask, said reflector having a mirrorized surface for reflecting light rays entering said interior through said transparent side portion into said diver's view for viewing objects outside said diver's normal field of vision.
A method for enlarging a diver's normal field of vision comprising the steps of:
In combination with a diver's mask having compartments each comprising a side portion of said mask and an interior for receiving a reflector having a mirrorized surface, each of said compartments having a transparent wall portion for allowing light rays to enter said interior of said compartment;
