When the headwear is not in use, the arms are stored adjacent to the front of the headwear and the reflectors are stored adjacent to sides of the headwear.

Abstract: A new helmet mirror comprises an articulated two-piece body having the mirror on one piece and an attachment device on the other piece. For most applications the attachment device comprises an adhesive for attachment directly to the clear face shield of a snowmobile helmet. The mirror and the adhesive are on the back of the respective pieces and the fronts of the respective pieces are smoothly contoured to reduce wind resistance and aerodynamic forces applied to the mirror body at high speeds. In an alternative embodiment a third piece comprising a link joins the mirror piece to the attachment piece with two articulation joints. The link is aerodynamically shaped to substantially reduce vibration of the mirror at high speeds and thereby reduce the forces applied to the articulation joints which retain the mirror in the proper viewing position.

Abstract: A circular rear view eyewear mirror, approximately 9 min. in diameter, consisting of a reflective surface permanently attached with epoxy adhesive to a cylindrical plastic base with one end obliquely cross-sectioned to form an ellipse. The angle formed by this oblique cross-sectioning of the base allows the rear view eyewear mirror to fit differing types of eyewear, including modern wrap-around sports eyewear. The elliptical end is attached semi-permanently to the rearward surface of the eyewear lens with double-backed adhesive tape. These elements, when assembled, are considered one piece in use and have no moving parts in relation to each other. The rear view eyewear mirror may be angularly adjusted by clockwise or counter-clockwise rotation before semi-permanent attachment by rotation upon the rearward surface of the eyewear lens. This adjustment of the rear view eyewear mirror allows for angular adjustment of the image seen by the wearer.

Abstract: An aerodynamic eyeglass lens piece which integrally combines a central inboard transparent section with laterally outboard mirror sections, thus enabling a forward facing user to see objects in front as well as behind. The lens piece sections form one agonic lens piece comprising: a light transmissive transparent section and fully reflective mirror sections. The mirror sections have an anatomical shape permitting unhindered over the shoulder viewing for bicycle riding. Several enhancements allow the lens piece to be interchangeable with tinted or clear alternatives. In the preferred eyeglass embodiment of the invention, the lens piece is selectively adjustable to a variety of operative positions. These enhancements serve to provide added versatility, fine tuning and custom fitting for the user. An alternate embodiment fits the lens piece to the existing sport helmet of the user.

In various embodiments of the invention, the ocular display apparatus is employed as a personal display of film, LEDs, fiber optics, CRT or electronic images generated for delivering data to a wearer as a virtual image at infinity.

Abstract: A unique mirror optical system reduces the anxiety of patients due to claustrophobia during magnetic resonance imaging or the like. A back surface mirror is mounted on a spectacle frame which is attached to the patient's head with an adjustable elastic band. With the patient in the supine position, the mirror allows the patient to see over the head or feet to scenes placed on a distant surface. Since the patient can see "out", the confined feeling which triggers the claustrophobia response is greatly reduced or eliminated.

Abstract: An integral rear view mirror for eyeglasses comprises an elongated channel formed within at least one temple piece of the eyeglass which supports an elongated rod having an upwardly extending tab. A notch is formed within the elongated channel and serves to lock the rod in a withdrawn position. The outwardly extending end of the rod supports a hinged attachment to a rear view mirror. A spring captivated within the channel urges the rod to the forward position. The mirror is rotatable between a downwardly extending in use position and an upwardly extending position when not being used. In addition, the mirror is rotatable to a position overlaying the most proximate lens of the eyeglasses to facilitate easy carrying of the glasses in the folded position.

Abstract: An optical device provides a unitary, functional eyewear device that enables the viewer to simultaneously receive both primary (on-axis) and secondary (off-axis) images. The optical device includes a primary lens, of a shape and size to be mounted in a frame and worn as traditional eyewear. This primary lens has some inherent reflectivity, transmitting some portion of the light reaching it, and reflecting the remainder. A secondary image mirror portion is preferably mounted along one edge of the primary lens so as to capture at least some desired portion of the light reflected from the primary lens. This secondary image mirror acts more as a true (opaque) mirror, reflecting some significant portion of the light impinging upon it. By proper alignment of this secondry image mirror adjacent the primary lens, some of the light initially reflected by the primary lens is re-reflected back towards the primary lens, where a portion of such light will be transmitted through the primary lens to the viewer's eye.

Abstract: A visual field image reflector attached to standard eyeglasses to extend vision into an impaired lateral visual field characteristic of a patient suffering from homonymous hemianopsia. The reflector is attached to the eyeglass frame adjacent the patient's nose, forward the lens for an eye having an impaired lateral field and displaced from the line of central fixation of gaze. The reflector includes a light-transmitting substrate and two differently tinted coatings. The first coating, near the patient's eye, is a partially-reflective and partially light-transmitting yellow tinted layer. The second coating, away from the patient's eye, is a light-transmitting, blue-violet layer. The reflected image of the lateral field is thus observed in yellow by the patient, and the portion of the central field image transmitted through the reflector is seen in blue-green.
