At the beach and in ski huts, cool people naturally wear „ink glasses“ to shield themselves from the sun’s blinding rays. When it comes to cool names, China’s „ink glasses“ (墨 mò „ink“ and 镜 jìng „lens; mirror“) clearly are in the top league of sunglasses. Incidentally, the Inuit used to put little knuckles or flat pieces of wood with fine slits on their noses to prevent snow blindness. And even the ancient Romans used sun protection for their eyes. In the first century AD, Emperor Nero supposedly always watched gladiator fights through green emeralds to protect his eyes from bright sunlight.
