Abstract: A ophthalmic fixation apparatus includes a case housing with an interior area to hold a power source, the case housing further having a switch to activate a first fixation element and a second fixation element; one or more straps extending from the case housing; a first flexible conduit extending from the case housing and to facilitate direction of the first fixation element; and a second flexible conduit extending from the case housing and to facilitate direction of the second fixation element; the ophthalmic apparatus is for use during an eye exam to keep the patient's attention and maintain a still eye for examination.

Abstract: An earpiece-less eyeglass apparatus and retainer-strap attachment mechanism. First and second attachment mechanisms are mounted on each side of a lenticular frame. Each attachment mechanism includes a stemball assembly, a socket housing, and a spring. The stemball assembly includes a shaft, a narrow neck, and a ball. The socket housing includes a primary socket, a secondary socket, and a narrow slot joining the primary and secondary sockets. The spring is mounted within the primary socket and the slot, and is shaped to form a rounded portion within the primary socket and a narrow restriction portion within the slot for receiving, respectively, the ball and the neck of the stemball assembly. The narrow restriction portion locks the ball into the secondary socket without placing stress on the housing when the neck of the stemball assembly is slid through the slot, moving the ball into the secondary socket.

Abstract: An earpiece-less lenticular eyeglass frame and removable retainer strap. Attachment mechanisms on each side of the lenticular frame enable a retainer strap to be directly connected to the frame. The retainer strap includes an end-piece at each end of the strap that is compatible with the two attachment mechanisms for attaching the strap to the frame and for removing the strap from the frame. A sliding clasp is used to adjust tension on the retainer strap for different activities such as reading or playing sports. A user may remove the retainer strap to interchange straps or to move the retainer strap from one pair of eyeglasses to another. The absence of earpieces makes the eyeglasses more comfortable, lightweight, less bulky, and less susceptible to damage.
