From Eyeglass Lenses to Optical Thin Films and Units:
Making Life More Convenient and Fulfilling
We were the first in Japan to commercialize vacuum deposition coatings for eyeglass lenses. Since then, we have led the industry with cutting-edge technologies such as high-performance lens coatings and advanced molding techniques that give lenses unique functionalities, turning "Wouldn't it be nice if..." ideas into reality. Building upon our foundation in lens coatings, we have expanded into optical thin-film coatings, glass molding, and comprehensive optical unit production, handling everything from design to assembly. Making life more convenient and fulfilling.: We respond to the desire for "Wouldn't it be great if we had this?" with reliable technology and quality.
The Itoh Optical Group aims to create high-quality products that are kind to both people and the environment.

We specialize in state-of-the-art coating technologies, high-performance lens molding, and innovative designs like specialty-shaped lenses. Beyond traditional vision correction, we aim to create lenses that enrich daily life. Meeting increasingly diverse needs is our strength.
Leveraging vacuum deposition technology cultivated from eyeglass lens production, we develop and manufacture optical coatings for components. Our work includes high-durability and heat-resistant films for automotive applications and high-precision coatings for new product R&D.
We produce glass aspherical lenses used in digital cameras, projectors, surveillance cameras, and medical devices. In collaboration with group companies, we handle everything from mold manufacturing to anti-reflective coatings in-house.
From receiver lenses to polarizing filters, we offer integrated services, including design, prototyping, and mass production, for various optical components across industries. We develop custom solutions tailored to clients' specifications.
Since pioneering hard contact lens manufacturing in Japan in 1958, we have achieved micron-level precision. Our lenses ensure safe, natural vision, contributing to advancements in eye care.
Since our founding in 1956, we have been able to continue our business thanks entirely to the support of our customers, business partners, local residents, and employees, for which we are deeply grateful. Carrying forward the founder's vision of "creating products that help people," we have contributed to society through a variety of products, primarily focusing on eyeglass lenses. Moving forward, we aim to continue advancing our technological development to help create more comfortable lifestyles. In the industrial sector, we will leverage our accumulated technological expertise to address challenges posed by the new era as a comprehensive optical manufacturer, focusing on developing and producing products that adapt to the diversity demanded by modern society.
