High-performing, custom-fit sports glasses, 3D printed from an infinitely recyclable, bio-based polymer, and biodegradable lens. Custom fitting, using current smartphone technology, elevates performance beyond legacy injection moulded ‘one size fits all’ eyewear, and gives any face shape, size or ethnicity, industry-leading ventilation and peripheral vision. On-demand manufacture, removal of persistent waste and no mechanical fixings, means a durable product that’s easy to maintain. All help contribute to a significantly reduced environmental impact at all stages of the products lifecycle.
