Abstract

The disclosure is an eyeglass frame including a straight relatively rigid bar having a plurality of notches disposed along its length, and carrying a generally U-shaped nose piece having a tab adapted to be inserted in and locked in the central notch in the bar. The bar also carries a pair of circular lens holders having tabs for insertion in selected notches in the bar so that the spacing between the lens holders and the lenses carried thereby can be adjusted. A headband is also provided having tabs for insertion in notches in the frame bar to hold the frame on the head of the user.
