Since the foundation of the company, we aimed for “Eye-Safety” as the core concept of product development and always created new markets by offering customers; industrial safety glasses including laser safety glasses based on the know-how of control optical properties, sports goggles, sports sunglasses and fashion eyewear. By now, the trademark “SWANS” has achieved the position of a world top brand in the sports industry. Presently, we as a comfort creating company, are expanding the scope of Vision Care by contributing to not only the sporting industry but also the whole lifestyle segment and we also implement various research associated with “People’s vision life”. By developing creative marketing strategies, we continuously endeavor to contribute to a healthy and safe environment that provides a rich and comfortable life for the people of the world.

- With the development of the company during the post-war economic recovery period, Yamamoto Kogaku’s anti-dust spectacles and safety glasses kept pace with the growth of the Japanese economy, providing industrial safety equipment for the steel, ship-building and automobile industries. In recent years, we have manufactured laser protective filters by utilizing proprietary technology to control laser beam properties and nowadays, we are distinguished as one of the few companies in the world to manufacture filters to block a variety of laser wavelengths. We developed not only eye safety equipment but also powered fan respirators and back support belts to protect workers from particulate dust and back pain. We also extensively promote our business in the international market.

Sportsmen and women are challenged under ever-variable weather conditions. These people are attached to the beautiful extent of nature that more often than not hides its infinite beauty away. SWANS supports their eyes through it’s own various technologies. SWANS offers lenses that are several times stronger than conventional lenses, dyestuff absorption technology blocks harmful light to the eye and anti-fog treatment secures clear vision under severe conditions. These product’s functions and precision have been tested in the great outdoors and SWANS chose only the products that passed these tests and satisfied all parties related to the world lineup. This is the method that SWANS uses when proceeding through product development.
