Improvements in the adjustable frames for spectacles, consisting essentially of providing the glass holder rings, on their upper edge, with a longitudinal groove, into which the corresponding end of a bridge piece is inserted with the possibility of sliding. Meeting of both rings, making the retention of the latter on that bridge piece by screws that pass through the rings by oblong holes, thus allowing the necessary mobility of said rings with respect to the bridge piece in question, to adjust their relative distance in accordance with the eye centers of the user.
