NOOZ weighs only six grams and is provided with a case which is precisely shaped, in which the backup reading glasses can be carried everywhere with you. By means of a small eyelet, the cover, which is supplied in various, fashionable colours, can be attached to the key ring or hung around the neck. The bridge is of non-slip elastomer and assures reliable, pressure-free grip on almost any nose shape. The glasses do not need a frame. The lenses are made of clear polycarbonate and are treated with scratch protection.
