Abstract

783,315. Spectacles. ZANETTINI, A. May 18. 1955 [May 18, 1954], No. 14388/55. Class 97(1) Spectacles for producing a distant virtual image of a near object have large sightcorrecting lenses 6, 7 each with a small prism 8 or 9 at its centre, so that the object may be observed through either the lens or the lens and prism and, so that rays coming from the object and passing through the prisms are refracted so as to assume on emergence from the prisms a direction such that they produce virtual images of the object. The lenses may be replaced by plain glass. The prisms may be attached to, or formed integrally with, the lenses, and the lenses may be rotatable in their frame 5.
