Abstract: Highly compact eyeglasses include a first lens portion and a second lens portion coupled via a bridge wire. Each lens portion includes an optical section, and may further include a transition section. The optical section may be characterized by a reference surface and an adjustment surface. From one pair of eyeglasses to another, the reference surface exhibits a constant curvature. The curvature of an adjustment surface is designed or chosen relative to the curvature of a reference surface to provide a lens portion associated with a particular overall dioptic power. The transition section may include a corrugation and/or a lip to aid in securing the glasses to a wearer's nose. The bridge wire serves as a type of spring that couples or interconnects the lens portions, where the spring includes and/or exhibits positional memory properties. The bridge wire may include bent or curved end segments, which may be embedded within the lens portions during a manufacturing process.

Abstract: Rimless eyeglasses having removable lenses. Each lens has a pair of bridge securing openings. The bridge is formed from a single wire. The single wire bridge is bent to form two c-shaped sections. Each c-shaped section is threaded through a respective lens, and ends of the bridge are inserted into one opening of the pairs of openings. A friction fitting secures an end of the bridge to a lens. Temples and nose pads are similarly secured to the eyeglasses. Each lens has a pair of openings for securing a temple and a pair of openings for securing a nose pad support. The temple has a c-shaped lens-securing member for engaging a pair of openings. A nose pad is mounted on the c-shaped nose pad support. The c-shaped nose pad support engages a pair of holes in the lens.
