| Abstract: |
Mirrorized compartments for extending a diver's vertical, lateral and posterior fields of vision. The mirrorized compartments are clamped on opposite sides of the diving mask and have mirrorized surfaces which reflect light rays entering the compartments from objects above, below, the sides or rear of the mask into a diver's view. In a first aspect of the invention, the mirrorized surfaces are fixed to provide supplementary lateral and posterior fields of vision of fixed amounts. In a second aspect of the invention, the mirrorized surfaces are rotatable about horizontal axes to provide supplementary vertical or lateral 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.
