A frame for spectacles having arms that can be opened out resiliently includes at least one lug and at least one arm which is articulated to the lug by a tie rod hinged to the lug and slidingly associated with the arm, a resilient device is active between the arm and the tie rod in order to urge the arm towards the lug. The resilient device includes at least one helical spring extending along a substantially longitudinal axis (K), corresponding to the direction of application of the resilient urging, and axes (L) of the turns of the spring are inclined with respect to the longitudinal axis (K) in order to confer on the spring a substantially flattened configuration transverse to the longitudinal axis.
