Calvin Klein Eyewear has boosted its eco credentials with its Naturals collection of spectacles and sunglasses inspired by the natural world, which are made from bio acetate.
The frames feature over 60% bio-based materials and sunglasses have Tritan Renew lenses that use up to 50% recycled content.
Chunky square and rectangular silhouettes standout for their smooth brushed surfaces, which have been given neutral, earthy colour options such as chalk, taupe and azure.
Models are branded with the Calvin Klein logo on the tapered temples and feature seven-barrel hinges.
