Abstract
A pair of foldable compact glasses comprising two frames for retraining two lenses therein and each provided with a hinge device at the outer side thereof, two temples each pivoting to the hinge devices, and a bridge device connecting the two frames. A height difference is provided between the hinge devices provided at the outer sides of the two frames so as to prevent the temples from overlaying and interlacing each other while folding and in aid of increasing the lens area, and/or the distance between the bridge device and wearer's nose bridge is increased so as to increase wearer's comfort. The glasses can be subsequently received within a rigid container after folding. This invention future discloses resilient nose pad devices for use in a pair of glasses, which resilient nose pad devices are tightly pressed against each other when the foldable compact glasses are folded so as to reduce overall thickness of the folded glasses.
