Nikon has been providing millions of people with a sharper point of view through the most trusted and sought-after optical products since 1917. While most people link Nikon with superior camera lenses, many do not know that we began manufacturing quality eyeglass lenses in 1946. Today, Nikon makes high index 1.74 double sided aspheric lenses. They are the thinnest and lightest lenses in this range.
