Abstract
An eyeglass apparatus comprises left and right eyeglass portions and a link. The link is configured to permit the eyeglass apparatus to transition between an extended configuration and a collapsed configuration. In the extended configuration, the eyeglass apparatus is adapted to be worn by a user in a conventional eyeglass wearing orientation. In the collapsed configuration: an inwardly facing lens face of one of left and right lenses faces an outwardly facing lens face of the other of the left and right lenses; a medial edge portion of the left lens is closer to a medial edge portion of the right lens than to a lateral edge portion of the right lens; and the lateral edge portion of the left lens is closer to the lateral edge portion of the right lens than to the medial edge portion of the right lens.
