Abstract

A pair of spectacles for providing a redirected view includes a visor configured to support a pair of triangular optical prisms attached to the bottom surface of the visor in front of a wearer's eyes. The prisms provide an internally reflected and refracted path approximately normal to the forward vision allowing the wearer to view scenes without head or body reorientation. The visor and the prisms are oriented at an angle of 5 to 15 degrees below horizontal, as defined by the spectacles' handle portion, to position the prisms at an optimal viewing angle to enhance wearer comfort. The prisms are made wide and spaced close together to provide a panoramic perspective, with the inside lower corner radiused to provide room for a wearer's nose.

the top surface of each prism is a mirrored surface,
an opaque coating is applied on the inner side of each prism, and each prism has a radiused portion on a lower inside corner;
two vertical side panels coupled to the visor one on each side edge, the vertical side panels sized to reduce light entering into the outer side of each of the pair of prisms;
