Curious and innovative: glasses made from natural materials
Do people who wear glasses care and know about the material of their glasses? Usually they are made of metal or plastic. The fact that glasses can be made from wood, buffalo horn or even beans is new. The Austrian television broadcaster ServusTV visited the ROLF eyewear manufacturer and gives an insight in the eyewear production processes.
Glasses made of beans, wood or stone - that sounds unusual, but the inventors from Tyrol show that it is possible.
