Mark O’Day was born with the idea of impacting on 4 main aspects of the current optical market situation: Quality, design, sustainability and price. Our sunglasses are made of 100% biodegradable cellulose acetate made in Italy. Cellulose acetate is made from processed wood pulp and cotton. Coming from wood pulp means that, unlike most man-made fibres, it comes from a renewable resource and is biodegradable.
