Colour
The rich brown Cola colourway is made by mixing organic color powder with raw biodegradable cellulose acetate. The result is a highly durable, hypoallergenic material, made from renewable resources. The crystal clear polished surface is achieved by tumbling the components of the frames in barrels filled with small pieces of wood coated with oil, paste, and other natural materials, and then hand-buffed.

Lens
The red hue in brown lenses improve depth perception and enhances contrast. This lens is a category 1, meaning it is not ideal in very sunny conditions, but great in overcast or even to give your eyes a bit of extra support indoors. All lenses feature anti-scratch and anti-reflective treatment with 100% UVA/UVB protection.

Made by renowned German lens- and optics manufacturer Carl Zeiss.
