Abstract
The invention is frames for an article of eyewear. The frames include a pair of earstems structured to extend along a side of the head and over ears of the individual. The earstems have a curved structure that extends around to a rear surface of the head such that distal ends of the earstems have a separation less than a width of the head. The earstems each define a plurality of elongate apertures located adjacent the distal ends and extending in a substantially vertical direction. The elongate apertures may have an elliptical shape and serve to enhance the flexibility of the earstems.
