FIELD: protective means for eyes, more particularly for protective screens, inspection holes, outfits for welders, metallurgists and firemen. SUBSTANCE: transparent material comprises substrate made of polymethyl methacrylate or polycarbonate. Layers of inorganic oxide such as tin oxide and metal such as copper or gold and outer layer of inorganic oxide such as chromium or tin oxide are applied successively onto said substrate. Material has high heat resistance and is transparent in visible spectral region. EFFECT: improved properties of the transparent material. 3 ex
