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.
