Abstract
A fashionable pair of spectacles with combined sliding and pivoting elements for viewing objects behind a forward facing user. The spectacles have temples at opposite ends of the eyepiece with longitudinal apertures for receiving closely fitting shafts. A pair of slender round shafts engage the apertures and have orthogonal forward end portions which project out of the apertures and receive reflective elements for viewing objects behind the user. In the first aspect of the invention, each reflective element is rotatably mounted to the orthogonal end of one shaft and is selectively adjustable by translating and rotating the shaft along and about the longitudinal axis of the corresponding temple aperture and by rotating the element about the axis of the orthogonal foward portion of the shaft. At the operative positions of the elements, the elements are in confronting relationship to the user and in front of the eyepiece and in the non-operative positions of the elements, the elements are in side facing relationship to the user and the eyepiece. In the second aspect of the invention each element is further adjustable by separating and rotatably attaching the forward end of the shaft to the other part of the shaft.
