Abstract
A rimlock for use with an eyeglass frame is provided. The rimlock comprises a pair of flanges which protrude from the frame at a split therein. A spring is fed through a bore passing through the flanges whereby a portion of the spring internal to the rimlock at a widened portion of the bore is in tension thereby biasing the flanges into engagement allowing the frame to hold a lens in position within the frame. By pulling the flanges apart, the lens can be removed.
