Lenses : materials
Today, the most used materials for the lenses manufacturing are ‘’organic’’, that is to say plastic. They offer a very good optical quality and present the advantage of being not very fragile and above all, very light.
Material and index
An index is associated to every material. Indexes go from 1.5, for usual materials, to 1.74, for ultra-high indexes.
The higher the index, the thinner the lens. Getting in thickness allows to get thinner and lighter lenses, so more aesthetic and more comfortable lenses.
Medium and high index lenses are more resistant than standard lenses. They allow a secure fit, well adapted to children and sportsmen.

Nikon offers you the widest range of materials on the market
All of them are accompanied with an excellent optical quality and most of them integrate a 100% UV cut. You will also find in the Nikon’s range the world's thinnest lenses.
Precursor in organic lenses, Nikon is indeed famous for the optical quality of its materials and for its lenses’ extreme thickness. Nikon is thus the inventor of the 1.74, the highest index of the world, and its range possesses the thinnest lens of the market with its aspherical 1.74 index.
Index 1.5 (CR 39) : standard material.
Index 1.6 (MR8) : 8 times as resistant as an index 1.5 ; integrated UV filter.
Index 1.59 (polycarbonate Moving) : 12 times as resistant as an index 1.5 ; integrated UV filter.
Index 1.67 : up to 40% thinner than an index 1.5 ; integrated UV filter.
Index 1.74 : up to 50% thinner than an index 1.5 ; integrated UV filter.
