What are acetate sunglasses?
With sunny weather in sight, now's the perfect time to take a closer look at why we use plant-based cellulose acetate in our premium sunglasses range. Read on to learn more and shop our collection.
Why is acetate a good material for sunglasses?
Cellulose acetate is a high-quality, non-petroleum-based plastic rendered from natural wood pulp and cotton fibres. Most high-quality designer sunglasses are made from this material, and we choose to use acetate in our premium sunglasses range because it is:
Glossy
Made from renewable resources
Durable
Lightweight
In addition, acetate retains its colour and brightness impeccably over time. This is due to the manufacturing method, where measured quantities of powdered pigment are mixed with acetone and kneaded into the raw acetate, either by hand or with large metal rollers. Unlike in regular plastic, where colour or patterns are usually sprayed on, the dye is embedded into the material before being cured, which prevents it from discolouring.
How are our acetate sunglasses made?
When they’re ready, computer-controlled mills cut out rough outlines of the sunglasses’ components from the acetate sheet. They are heated, and metal hinges, nose pads and other design features are pressed into the temple and arms. The frames are cut again, then are smoothed by hand to match the shape of our design.
To be polished, the components are placed into barrels full of wood chips and small stones, where they tumble together for hours before each piece is hand-buffed to achieve a glossy finish. Hinges and arms are attached with small screws, and the frames are inspected to check the shape of the temple, and to make sure that the ends of the frame line up neatly with each arm. Lastly, the lenses are inserted, the sunglasses are waxed to add shine – then they are ready to wear!
