Nikon, whose name is synonymous with “the world's finest lenses”, has been providing millions of people across the world and beyond with a sharper point of view through the most trusted and sought-after optical products since 1917. In order to foster innovation, The Nikon Core Technology Center focuses on Opto-electronics and precision technologies. It has introduced the first ultra-high index lens: index 1.74 double-sided aspheric lenses as the thinnest and lightest lenses in the market: and the first clear lens that filters blue light—SeeCoat Blue, which enhances contrast for screen readers. Over the years, Nikon has proved that it can deliver outstanding performance in the most extreme conditions and has earned the status of a legendary brand. To celebrate its 100th anniversary in 2017, Nikon Lenswear exclusively launched the Kateo and AI Series for Puyi Optical, combining clear and thin materials with sharp designs and high performance coatings, providing Puyi's clientele with outstanding vision quality.
