Abstract
Abstract Eyewear such as sunglasses comprises a one-part lens and a frame therefor having a continuous channel therearound into which the lens is receivable. Preferably at least one of the lens and the frame are elastically deformed when the lens is engaed in the frame, so tending to strengthen the lens-frame combination. Suitably the channel has a non-uniform depth in preselected portions along its length, whereby different frames may have a different appearance while utilizing identical lens. The frames suitably include a gate which may be opened to provide access to the channel when inserting or removing the lens.
