Carefully finished sustainable acetate sunglasses with triple barrel sprung hinges and curved arms to ensure flexibility and a snug fit. The Otus is made with Mazzucchelli bio acetate, a naturally derived material providing a more eco-friendly alternative to petroleum-based plastics. Cellulose acetate is made by extracting cellulose fibres from cotton or wood pulp to create a transparent paste. This paste can then be coloured and molded into our beautiful frames – it’s magic!

+ Blue Light Lenses

With an abundance of phone screens and endless zoom meetings, our eyes can end up being stimulated for prolonged hours. This over consumption can leave our eyes feeling strained, and our minds fatigued. Wearing lenses that filter the higher energy blue light can help you concentrate and feel more relaxed at the end of each day. So if you’re suffering with tired eyes, a pair of blue birds can lend you a hand.
