About SEYU

SEYU is an emerging sunglasses label founded by two Zurich students. SEYU is dedicated to developing fashionable and trendy designs and creating social value for our environment. Therefore, SEYU donates 5% of its sales to three charities each in the field of oceans, nature and health. All designs are created in Switzerland and are timeless, stylish and of excellent quality. For this, SEYU uses only the finest acetate materials from Italy.


SEYU sunglasses are all made of acetate. Acetate, or more precisely cellulose acetate, is a vegetable plastic from which the main parts of the frame are made. This material is extracted from cotton and transformed into cellulose acetate. The basic base of the material is transparent. The colors are created with organic color powders, which are applied to the material. Depending on how opaque the color should be, this process is repeated as often as desired. SEYU sources its material from a sixth generation family business in Italy.
