How Eyeglass Frames Are Made by Hand in Jura, France

In Morez, population five thousand, in the Jura mountains near the Swiss border, spectacle-making dates to 1796 when a nail-maker bent wire into a frame. Today houses like Gouverneur Audigier continue producing frames by hand from acetate, horn, and precious metals, maintaining Morez's reputation as the historical capital of French eyewear.

Acetate, from cotton fibre and wood pulp processed with acetic acid, is produced primarily by Italian manufacturer Mazzucchelli. The material accepts vivid colours and complex patterns, making it far more expressive than injection-moulded plastic.

Hand-finishing involves tumbling rough-cut pieces in barrels with pumice for days, then buffing individually on cotton wheels. This creates the deep, translucent lustre distinguishing handmade frames from mass-produced counterparts. The warmth of acetate against skin contributes to wearing comfort.

Horn frames represent the pinnacle. Natural horn from water buffalo is heated, split, and pressed into sheets. The natural variations ensure no two frames are identical. Horn is remarkably light, hypoallergenic, and develops a polish with wear.

Fitting involves heating and bending, which acetate and horn accommodate gracefully. A skilled optician can tailor temple bend, nose pad angle, and pantoscopic tilt to the individual face, creating fit mass-produced frames cannot match.

The economics are under pressure from Asian mass production, which has captured over ninety percent of the global market. Surviving workshops compete on quality, customisation, and the intangible value of wearing something made by identifiable hands.
