Balenciaga Demo Pilot Unisex Eyeglasses BB0117O 003 57

Balenciaga Demo Pilot Unisex Eyeglasses BB0117O 003 57 is a unisex pair of frames. Frames are bought on fit as much as looks: the three numbers printed on the arm — lens width, bridge, arm length — decide whether they sit right. An optician can adjust nose pads and arms in a minute; a frame that slips is usually a fitting issue, not a design one. Where one is discounted, compare the size and edition rather than the headline alone. Clean with lens spray and a microfibre cloth, and keep them in a case — coatings scratch more easily than the lens beneath them. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
