Abstract: Some embodiments are directed to a hinge for spectacles including an optical frame front and at least one temple linked to a tenon of the optical frame front, the hinge including a first part linked to the tenon and a second part linked to the temple, the first part and the second part being linked by a link device mounted along an axis of the hinge and being movable between an open position and a closed position; when passing from the open position to the closed position, an opening is formed between the outer surfaces of the first and second parts. The first and second parts each include a conduit opening opposite each other in the open position, and the hinge includes a hinge member mounted along the hinge axis between the first part and the second part.
