McCartney to launch eco-friendly sunglasses

London: Fashion designer Stella McCartney will launch a line of eco-friendly sunglasses next year.

The British designer, who is a vegetarian and refuses to use leather or fur in her creations, revealed the new collection will be made of more than 50 per cent natural and renewable materials. "The greatest challenge was the amount of time that was spent on research and testing to get the best quality product possible with the highest performance in terms of resistance, while still maintaining the style and finish we always try to achieve," femalefirst.co.uk quoted the 40-year-old as saying.
