Abstract: A frame assembly for eyeglasses is provided wherein the overall width of the eyeglass frame is adjustable by utilizing a telescoping brow bar. The upper frame member or brow bar is formed to include either a pair of telescoping or indexed joints allowing the length of the brow bar to be adjusted thereby placing the hinge points and temple bars further apart from one another. The adjustable length of the brow bar provides excellent adjustability of the overall width of the eyeglass frame in simple mechanical construction. Further, in a unique method of forming the adjustable brow bar assembly a central portion may be formed in a first molding step and an adjustable hinge section is then molded directly over the central portion in a second molding step. The present invention utilizes in-mold-assembly techniques to reduce the assembly steps required to form such an adjustable brow bar assembly while further resulting in an eyeglass frame that has increased adjustability and utility.

Abstract: A method and device for optically stimulating the visual system during static perimetry and for objectively evaluating adequate stimulus-related electrophysiological and/or magnetophysiological quantities. Light stimuli with defined parameters derived from a predetermined correlation function and from the known intensity dependence of the excitation response amplitude are presented to the observer. The excitation responses contained in the ERG and/or in the EEG/MEG are detected and processed. These excitation responses are used to determine and topographically evaluate the local sensitivity of the visual system. In one embodiment, the light sources are fixed inside a perimeter, and the excitation responses are amplified and digitized by a device, which preferably comprises an ERG/EEG measuring system and an A/D converter.
