Abstract
An eyeglass frame in which the rims are openable at their inner (nose) sides. A slot is defined between a pair of pins extending between the rims. A latching member is pivotally mounted on one of the pin and hooks onto the other pin in its closed position for closing the rims and clamping the associated lens therein. An overlay member may be provided on the visible side of the latching member.
