HOME › World’s highest refractive index plastic lens 1.76 Material
The world’s highest refractive index plastic lens 1.76 material, created by the advanced material development technology of TOKAI OPTICAL, a specialized manufacturer of eyeglass lenses, has been used and loved by many people around the world for a long time. The 1.76 material, which boasts the world’s highest refractive index among plastic lenses, has been highly evaluated in markets around the world for its “amazing thinness” and “outstanding comfort” since the introduction of the double-surface aspheric design, and continues to lead the spectacle lens scene.

In the 1.76 material category, we have developed LUTINA, an eye care lens that takes eye health into consideration, as well as the latest designs for progressive addition lenses using Neuroscience technology and occupational lenses for intermediate-distance. We also offer many secondary processing options such as ultra-low reflection coating and scratch-resistant coating. TOKAI OPTICAL is proud to be able to recommend these spectacle lenses to our customers.

More than 15 years have passed since the 1.76 material lens was commercialized and introduced to the world, and Tokai Kogaku will continue to support comfortable and happy vision for people around the world. We will continue to take on the challenge of developing eyeglass lenses that enrich people’s lives.
