SWANS was introduced in 1972 when Yamamoto Kogaku, which got its start in 1911 as a maker of eyeglass lenses in Osaka, saw the need to apply its technologies to the sports scene. SWANS technologies, built up by Yamamoto Kogaku over a history of more than 110 years, deliver a diverse lineup of products that protect safe, comfortable vision for not only top athletes but a wide range of users.
