The invention relates to a novel method of designing and producing eyeglass-type sun or viewing glasses (Fig. 1) in which two lateral cords (3) replace the standard arms. The aforementioned lateral cords are fixed directly to the glasses (1) and are hooked over and behind the ears. Said cords are subsequently anchored in place in the natural half-cone formed at that point with the head, using a suitably-shaped end piece (5, 5'). In this way, the glasses are pressed against the face and nose rather than being supported by same and can be spontaneously adjusted. Several methods of fixing the cords to the glasses have been considered, in particular methods whereby the fixing elements are removed from the field of vision (Fig. 5 and 6), thereby increasing the latter.
