The Ghost in the System: Where Free Will Lurks in Human Minds

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. The bridge wire may further include an indentation segment, which may provide a secure holding region or section during manufacture, and which may additionally help to maintain the eyeglasses in a given position upon a wearer's nose.
