The size of the lenses and the curved shape of the glasses are designed to optimize the protection of the eyes. MAVIG uses only protective lenses of the highest quality. This guaranties the best light transmission values and a maximum lens break resistance. An ideal composition of the protective material results in a high level X-ray absorption, and optimized production processes achieve an absolute homogeneous allocation of the glass additives. The quality features of our glasses make them perfect for the use in the medical environment: Great frame stability through high-grade synthetic materials Optimized balance of sturdy, light-weight frame and lenses Minimized risk of injury due to shape and used components No softeners used throughout the entire manufacturing process Low allergy risk due to carefully chosen materials Easy cleaning and superior resistance against chemical influences (disinfection) Robust and durable finish coating Additional anti-reflective coating for the lenses possible Due to the highly curved frame, corrective lenses are unfortunately not available for this model.
