rh+ acquires and uses pentapolar technologies and the technological style developed by Polygon.Polygon offers a product with high visual and protective performances for urban use and leisure.  The rh+ Polygon lenses guarantee very high protection thanks to the polarized filter that allows efficient shielding from glaring light rays, and thanks to the anti-reflective treatment that reduces the glares of light inside the lens.  The treatment of mirroring or graduated mirroring applied on the upper and lower part of the lens leaving the central part free ensures greater visual contrast.The rh+ Polygon frames are made of Polygore material, a high performance technopolymer, whose chemical stability allows heat resistance, resistance to deformation and excellent electrical insulation properties.   

Thanks to the use of this material, the frames are light, flexible, resistant and stable in a wide range of temperatures and frequencies.
