Abstract:
An optical eyewear for providing a wearer with a redirected field of vision when the wearer assumes a normal frontal viewing line of sight, said optical eyewear comprising:an eyewear frame including having a rigid opaque planar visor with a pair of laterally spaced temples hingedly connected to and extending rearwardly thereof for supporting the visor on the wearer with said visor extending substantially parallel to and above said normal viewing line of sight with a lower planar surface of said visor substantially normal to the face of the wearer;a pair of prismatic elements connected to said lower planar surface of said visor in laterally spaced relationship in front of each eye of said wearer, each of said prismatic elements having an optically clear rectangular vertical surface facing said wearer, a rectangular horizontal surface with a reflective coating at said lower surface of said visor, and a rectangular optically clear inclined surface interconnecting said horizontal surface and said vertical surface, the angularity between said surfaces of said prismatic elements and the optical characteristics thereof being such that images in the redirected line of sight are reflected at said horizontal surface, internally reflected at said inclined surface and refracted at said vertical surface to the eyes of the wearer thereby providing a redirected view normal to said line of vision, the adjacent inner side surfaces of said prismatic elements being translucent and sufficiently closely spaced to provide a continuous lateral field, the outer side surfaces being sufficiently closely spaced to provide unobstructed lateral peripheral vision, and the lower edge of the vertical surface terminating slightly below said binocular view field thereby providing unobstructed lower peripheral vision sectors whereby the wearer may achieve the redirected line of sight without loss of sensory aspects of normal peripheral vision.
