British brand Bird Eyewear has launched Birdies, a sustainable range of ophthalmic frames and sunglass styles for children.

The frames are made from processed castor beans, a new natural polymer that is lighter than aluminium and often used in vehicles. The durable frames can be supplied with lenses featuring 100% UV protection or a blue light filter for screen protection.

A company spokesperson said: ‘These frames are virtually indestructible. Designed to withstand rough treatment, they’re bendable, throwable, and come with impact and shatter-resistant lenses. The low-density material is 10 times stronger than the plastics in car bumpers and 13 times stronger than common bioplastics.’
