Abstract: The expandable and flexible bridge member is adapted for use a a part of clip-on sunglasses. It permits the sunglasses to be mounted on any eyeglasses, including those with a protruding bridge, with the bridge member of the sunglasses in alignment with the bridge of the eyeglasses. The bridge member can take the form of a uniquely shaped spring with a shrink wrapped plastic sleeve or one or more strips of elastic or rubber-like material. The bridge member is provided with a bridge engaging capability so that proper alignment is maintained with the eyeglasses bridge. The bridge engaging structure may take the form of a recess or a hook.

Abstract: The eyeglasses frame is provided with spaced engaging parts. The lens sections of the sunglasses are provided with an enclosed spring bridge mechanism that permits the lens sections to be moved toward each other, compressing the spring, to insert the sunglasses between the engaging parts. The spring urges the lens sections away from each other, to cooperate with the engaging parts, to mount the sunglasses on the eyeglasses frame.

Abstract: The eyeglasses frame is provided with spaced, oppositely extending, coplanar recesses. The lens sections of the sunglasses are provided with first and second oppositely directed collinear protrusions. An enclosed spring bridge mechanism moveably connects the lens sections. The spring bridge mechanism permits the lens sections to be moved toward each other, compressing the spring, to insert the protrusions into the recesses. The spring urges the lens sections away from each other, seating the protrusions into the recesses, to mount the sunglasses on the eyeglasses frame.

Abstract: The lens sections of the sunglasses are joined by a spring mechanism. The mechanism includes first and second concentric tubular members. Each member is affixed to the rim of a different one of the lens sections. The members enclose the spring which urges the lens sections toward each other, such that prongs mounted on the rims can engage an eyeglasses frame to mount the sunglasses thereon.

Abstract: The present invention is addressed to solving the problem of AR coating lenses having at least one or more. textured translucent regions, without altering the effectiveness of the translucent regions to reduce glare. A part of the uniqueness of the present invention is that the AR coating is applied on the surface that opposes the translucent region. As such, part of the invention is the discovery that AR coating the lens on the surface opposing the translucent regions does not limit its ability to block glare inasmuch as the coating does not alter the surface contour of the translucent region.

Abstract: The clip-on sunglass assembly mounts on eyeglasses and has mirror image frame parts. Each includes a lens retaining frame portion with a set of protruding “L” shaped eyeglass engaging prongs and a bridge element. A mechanism is provided for connecting the bridge elements for movement between a proximate position, where the frame parts are relatively close to each other, and a remote position, where the frame parts are relatively far from each other. The connecting mechanism includes at least one coil spring situated within a cylindrical enclosure. The frame parts are normally biased toward each other by the spring such that the prongs securely engage the eyeglass frame. In one preferred embodiment, the enclosure has an open end which receives the bridge element of one frame part. The spring is operably situated between the enlarged end of the bridge element and the interior wall of the enclosure, adjacent the open end.

Abstract: The clip includes a base to which a bistable sunglass lens carrying frame is mounted. The frame is moveable relative to the base between operative and inoperative positions. A “U” shaped spring biases the frame toward each position. First and second parts are mounted on the base for rotation in parallel plans, about a common axis perpendicular to the base, such that clamping arms extending from each of the parts are moved relative to clamping arms fixed to the base, between a position in which the clamping arms are proximate to each other and the eyeglasses are securely clamped therebetween, and a position in which the clamping arms are remote from each other. The spring also biases the parts toward the clamping position. The components are easily assembled, being held together by a single conventional fastener, in the form of a screw or a press-fit pin.

Abstract: The present invention is addressed to a method for fabricating lenses having at least one or more translucent regions used to reduce glare and/or increase visual acuity. To overcome the limitations of the prior art, an injection mold die having a selective portion thereof textured with a pattern or so-called "texture," which is replicated on the lens during injection molding, is employed to form a region of desired translucency on the finished lens. Various methods may be employed to fabricate the texture or pattern on the desired surface portion of the mold die, including mechanical engraving, chemical etching, and electrical-erosion machining (EDM and ECM). Typically, the texture or pattern includes multiple grained features of a quasi-repeating geometrical pattern distributed on the selected portion of the mold die.

Abstract: Each side of the multi-sided freestanding rotable rack includes a first section, with a first indicia representing a particular eyeglass frame style, and a plurality of second sections. Each of the second sections includes a second indicia representing a different sunglass lens type suitable for a particular activity. A retainer for clip-on sunglasses extends from each of the second sections. The retainer holds clip-on sunglasses suitable for the eyeglass frame style indicated by the first indicia of the side upon which it is located and for use in the activity represented by the second indicia associated with the second section upon which it is located.

Abstract: Spaced prong arms, spring loaded toward an initial position, are moved relative to fixed prong arms, against the spring force, to a position for engagement of opposing sections of the eyeglasses frame. The ends of the prong arms are shaped to receive the frame. The spring force causes the prong arms to securely retain the eyeglasses frame. In one embodiment, the moveable prong arms are associated with a coil spring. Movement of the prong arms compresses the spring, which urges the prong arms toward an expanded position. In a second embodiment, the moveable prong arms are leaf springs. The springs flex to permit the frame to be inserted. The ends of the prong arms may be plastic coated to protect the eyeglasses frame.
