Swannies frames are made from premium cellulose acetate, the industry standard for premium eyewear.* Acetate is a BPA-free plastic derived from natural materials including wood pulp and cotton fiber.
As your glasses will be coming into contact with your face for long periods of time, acetate is a great non-toxic alternative to petroleum-based plastics and is hypoallergenic, providing a more natural feel for your skin.
Acetate is also a malleable plastic which can be heated and reshaped multiple times.
Like many personal products, regular maintenance will keep your Swannies in tip-top shape.
*Exceptions: Fitovers (TR-90 frames) and metal-based frames.
As acetate is a soft plastic, it can become misshapen by exposure to high temperatures and regular use.
Please keep your Swannies in a cool, dry place. Do not leave in a hot car, for example.
If your acetate Swannies appear to be uneven, you can follow the video below to re-adjust them, or you can also take them to an optometrist or eyewear store for readjustment by a professional, many will do this free of charge or for a nominal fee.
Clean your Swannies lenses with a clean, lens cleaning cloth and lens-cleaning spray. Swannies can also be washed in warm soapy water.
Do not expose your Swannies to harsh chemicals as this may strip the special coatings on the lenses.
