Abstract
Eyeglasses are provided for folding into a substantially flat configuration to be fitted inside a compact case. The eyeglasses include a frame surrounding a pair of lenses, and a pair of temples which extend from respective outer edges of the frame. A first hinge connection positioned on each temple allows outer parts of the pair of temples to be folded horizontally inwards from the unfolded configuration into a first folded configuration. Respective inner parts of the temples are rotatable downwards relative to opposite side edges of the frame about respective second hinge connections into a fully folded condition substantially coplanar with the frame. In some embodiments, the frame and tips or earpieces of the temples are of rigid plastic material while the temples and hinge connections are of metal.
