The Italian eyewear group Thélios has entered an exclusive, long-term partnership with the British designer Stella McCartney. Under the agreement, Stella McCartney will collaborate with Thélios on sustainable innovation in the eyewear category.

Thélios will develop, manufacture and distribute Stella McCartney eyewear beginning with the spring/summer 2021 collection, which will be available from November 2020. The first collection will incorporate sustainable features, including bio-lenses composed of 39 percent castor oil, with carbon reduction emissions of 40 percent on the raw material.

Additionally, the frames will feature a version of bio-acetate composed of fibers derived from wood and cottonseeds, plant-based plasticizers and 68 percent organic carbon content.

Thélios is owned at 51 percent by LVMH and 49 percent by Marcolin. In July 2019, the French fashion group reached an agreement to further develop the Stella McCartney brand, which is committed to sustainable and ethical luxury fashion.
