Stella McCartney's new specs appeal Britsh designer Stella McCartney will launch her first range of optical glasses in March. Stella McCartney is set to launch her first collection of optical eyewear in March. The British designer already has a line of sunglasses, which launched in 2003 and have been extremely popular. The collection will consist of five styles and draw inspiration from McCartney's signature masculine-meets-feminine aesthetic, using a warm colour palette of burgundy, taupe, black, teal. READ: Stella McCartney awarded OBE in 2013 New Year Honours List As ever, she's keeping up her green credentials by using the same bio-acetate used in the sunglasses range, which are made of 54 per cent natural sources. The product's formula combines cellulose, the most common organic compound on Earth, which is renewable and biodegradable, together with natural plasticizers, which differ from DEP (Diethyl Phthalate), as they derive from citric acid, a natural substance obtained through a fermentation process.

If you actually take a moment to look around, you are surrounded by optical both as a necessity and a statement. It is exciting because it says something new, all ages express themselves through optical. Prices will range from £149 to £157, and will be available from high-end retailers and opticians.
