The tinted lenses have been created by two layers of different hues. Each coloured lens is fixed to the opposite corner of the frame, with one positioned over the other to create a deep overlapping effect. This technique has been possible thanks to the exceptional ability of Inui Lens, a Japanese manufacturer specialised in sunglasses with over sixty years of experience. The glasses come in a soft leather case which is secured by using a temple as a fastener, and which includes a lens-shaped cleaning cloth.
