Description Lens Technology Nikon offers extensive expertise in these three areas, providing lenses that offer superior visual performance and unsurpassed protection. Design Nikon is a leader in ophthalmic lens technology, holding claims to a series of firsts, from High-index 1.74 material, to the first customized single vision lens. Nikon continues to strive to be a leader in technological advancement in the ophthalmic lens industry, with the development of advanced digital lens designs and innovative coatings. Materials High-index materials offer the highest quality technology available in eyeglass lenses. Nikon pioneered this technology by introducing its highest index material available, 1.74. Coatings Nikon has an extensive and illustrious history in lens coatings that spans industries as diverse and specialized as photographic equipment, high-precision instrumentation and micro-computer technology. This impressive heritage gives Nikon the leading edge in the field of ultra-thin coating technology for optical lenses. Nikon coatings are the result of a rigorous process that guarantees quality, durability, easy maintenance and of course, unequalled optical performance. Nikon offers a variety of coatings to consumers and all Nikon coatings assure three primary benefits. Superior Scratch Resistance Nikon coatings protect lenses against abrasion and scratches, thereby prolonging their life whatever their index. Advanced Light Control and Anti-Reflection Nikon coatings eliminate reflections. They enhance visual clarity particularly when driving at night and working on a computer, keeping residual reflections to a minimum. Furthermore, Nikon coatings limit interference fringes by matching varnish to a material’s refractive index. Long-lasting, Easy-to-Clean Performance The superior water and dust-repellent properties of Nikon coatings prevent lenses from water tarnishing and make cleaning quicker and easier than ever.
