Gucci GG0746S 005 57/17 Blue & Beyond sunglasses. Introduced for the first time in the luxury eyewear industry, the Blue & Beyond project consists in the combination of high-end iconic frames with qualitative dual-innovation lenses that are specifically conceived to relieve intense eyestrain both indoors and outdoors. The double benefit of the product derives from the pioneering combination of distinctive styles with smart lenses characterised by a blue-light-filtering treatment with photochromic technology, which allows to reduce the impact of high-energy light from laptops and digital devices, while also protecting the eyes by darkening the colour when exposed to sunlight.These have a Rectangle / square frame shape and made from quality acetate. The frame colour is Black with Yellow lenses. The lens width of these sunglasses is 57mm. All of our frames offer 100% UV protection and include a case and cleaning cloth. Many are available with prescription lenses too.
