| Abstract: |
A diving mask with supplemental lateral and posterior fields of vision. A pair of compartments which extend outwardly from opposite sides of the diving mask have fixed mirrorized surfaces which reflect light rays from objects at the sides and rear of the mask into a diver's view. In a first aspect of the invention, the fixed mirrorized surfaces are parallel to a front portion of the mask. In a second aspect of the invention, the fixed mirrorized surfaces extend outwardly and rearwardly from the opposite sides of the mask. In a third aspect of the invention, the fixed mirrorized surfaces extend outwardly and forwardly from the side portions of the mask. The compartments are preferably separately sealed to preserve the reflectance of the mirrorized surfaces, prevent fogging and avoid the necessity of cleaning.
