An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.

A method for cutting-out a multi-layer ophthalmic lens () following a desired contour (C), includes: a step of pre-blanking the ophthalmic lens () using a preliminary tool (), according to a preliminary contour (CC); a step of blanking the ophthalmic lens () using a blanking wheel (), following a blanking contour (CC); and a step of finishing the ophthalmic lens () using a finishing tool (). According to the invention, the preliminary contour (CC) is larger than the desired contour (C), and the blanking wheel () used has a granulometry of between 0.1 and 0.5 mm and is controlled in relation to the ophthalmic lens () so as to apply a radial force of between 0.1 and 5 N to the ophthalmic lens () during the blanking step.
