With frames weighing less than 3 grams, AIR Titanium spectacles are the world's lightest, made from a nickel-free titanium wire with a diameter of only 1mm. The optimum characteristics of the titanium material provides the spectacles with an exceptional flexibility and strength and offers endless scope for adaptation of the spectacles to the faces of individual users. The design is minimalistic - no screws, rivets or soldering. Simply a wire bent and shaped into a pair of spectacles, which can either appear almost invisible or more distinct depending on the model chosen.
