Abstract: A pair of eyeglasses or sunglasses in which there are eyeglass frames having a pair of support arms hinged therefrom. Each of the support arms has disposed between the ends thereof hollow resilient fluted coupling members having a plurality of linearly disposed contiguous flutes adapted to be adjustable in at least two different positions including a first position in which the flutes are closed to provide a first arm length, and a second position in which at least some of the flutes are open to provide a second arm length that is longer than the first arm length.
