For our frames we exclusively use UV400 certified sun glasses with 70% light absorption and without antireflection coating. The material of the sun glasses depends on the type of frame and its glazing.
In our full frame frames from acetate we standardly use sun glasses synthetic material from CR39, while all frost f-type and myfrost frames are exclusively processed with polycarbonate (a more robust synthetic material).
You will receive the color of the sunglasses as seen in the online catalogue.
