Abstract: A method for assembling eyeglasses is disclosed. The method consists of selecting a pair of lenses from an inventory of circular lenses according to a patient's prescription. The circular lenses have the same geometric and optical center, so they do not require ground (grinded) decentration. The round shape also allows the lenses to be rotated within the eyewires when the clasps are open. The lenses are mounted into the annular eyewires of the eyeglasses, rotated so that the cylindrical axis is appropriately aligned, and secured in place so that the lenses may not rotate. The correct pupillary distance is achieved by varying the width of the nosepiece. Bifocal lenses may be selected based on the patient's bifocal prescription and positioned on the existing lens according to the bifocal markings on the eyewires.

Abstract: A pair of eyeglasses which resist fogging are disclosed. The glasses may be a rimless design or a fully framed design. In each case, the glasses have a right upper lens rim and a left upper lens rim. Left and right lenses, each having front and occular sides, are supported by left and right upper lens rims, respectively. A bridge interconnects the right upper lens rim with the left upper lens rim. Each lens rim defines a plurality of apertures, displaced 70-90° from a horizontal viewing angle passing through the approximate center of the lens, to allow passage of air at the occular surface of the lens to limit fogging. In some embodiments, the temple arms are provided with enhanced gripping distal portions. The left and right temples, each extending from an outboard side of respective lens rims, terminate in a distal portion having a subtle S-shape for engaging the mastoid of the wearer. Preferred embodiments are useful as sport-glasses, with or without corrective and/or colored lenses.

Abstract: An apparatus comprising a nosepiece coupled to a pair of annular eyewires, and a pair of clasps hinged to the nosepiece that cooperate with each of two annular eyewires to secure the lenses. Each clasp and eyewire contains a locking hole into which a pin may be inserted to secure the clasp in the closed position. The eyeglasses also contain a pair of temples, each of which is pivotally joined to each of the eyewires. The eyewires have axial markings that indicate the cylindrical axis of the lenses, and bifocal markings that indicate the correct position of the bifocals, so that lenses may be installed and removed without the need for instruments or tools.

Abstract: A system for attaching optical frames and lenses is described which provides positive, reversible attachment without rims, cords, or screws. The mating is performed with a mechanical closure onto a receiving portion of the lens which has been formed as the mating piece for the closure device. Lenses may be changed and adjusted in a straightforward manner and the resulting device presents a clean, fashionable appearance without the need for structural rims, cords, or screws.

Abstract: A pin assembly for use in securing lenses within the frames of eyeglasses is described. The assembly includes a pin having a head and a barrel and further includes a securing ring. The securing ring has a channel therethrough which includes a series of projections. An additional series of projections are formed on the barrel of the pin. Thus, when the pin is mounted within the frame of the glasses, the securing means is placed over the barrel so that the projections within the securing ring and the projections on the barrel cooperatively interact to permanently secure the pin assembly into the eyeglasses frame. This also insures that the lens is permanently mounted within the eyeglasses frame. The projections on the barrel of the pin and within the securing ring are oriented such that the user can slide the ring onto the barrel of the pin but can not remove the ring once the projections come in contact with each other.

Abstract: A lens includes a central nose frame having a top wall and spaced first and second side walls directed to the top wall at predetermined obtuse included angles, with first and second cup-shaped lens frames mounted to opposed sides of the nose frame to receive removable lens members respectively therewithin. First and second eyeglass legs are hingedly mounted to the respective first and second lens frames and arranged for abutment, in a complementary manner, the first and second sides of the nose frame, to include a lock bar pivotally mounted to the nose frame to extend over the first and second nose frame sides, as well as first ends of the first and second lock legs to secure the lock legs and the associated lenses within the frame structure.
