ABOUT SWANS

Made in Japan

Taking responsibility for safety and comfort

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 105 years, deliver a diverse lineup of products that protect safe,
comfortable vision for not only top athletes but a wide range of users

Products made in Japan

Almost no other manufacturer in the world is able to handle development and production entirely in house, from design of lenses based on specialized optical expertise through designing frame layouts capable of bringing out maximum lens performance.
Thanks to these technologies, we are able to design and produce eyewear suited to a wide range of purposes, from the ground up.

Lens technologies for controlling light

The polycarbonate lenses used in SWANS products deliver outstanding transparency, shock resistance, heat resistance, and incombustibility. SWANS lenses, which deliver outstanding optical performance, are molded from this resin, also used in applications such as bulletproof equipment and aircraft canopies, using advanced molding technologies. In addition, not only do SWANS lenses block out 99.9% or more of harmful UV rays, but they also deliver a wide range of lens functions essential to individual uses, such as petroid lenses that realize the high strength needed in sports, Ice Blue lenses that improve visibility using technologies to control light rays at specific wavelengths, polarizing lenses that secure clear visibility by controlling glare, and Claritex-coated lenses that maintain visibility by controlling adhesion of rain and perspiration.

Lens technologies for controlling light

UV rays can cause severe damage not only to the skin but to the eyes as well. It has been pointed out that exposing the eyes to strong sunlight over a long period of time results in more than just painful irritation—it also is one cause of disabilities of the eyes. All lenses used in SWANS products (with the exception of some special-purpose Yamamoto products) block 99.99% or more of harmful UV rays—no matter which lens color you choose.

These lenses are equipped with special filtering functions that effectively block out glare in the vision due to diffuse reflection of light from the sun and other sources. Specifically, they enable a clear view of unevenness in the road by restraining glare from the road’s surface, make it possible to see inside buildings and other structures by reducing diffuse reflection of light on windows, and make it possible to see fish and underwater features by reducing glare from the water’s surface.
In addition, unlike low-priced polarizing lenses, which are susceptible to water damage and lack durability, Yamamoto Kogaku’s polarizing lenses have the durability needed for use in a wide range of outdoor recreation environments (including uses in extreme temperature and humidity and underwater).

Photochromic lenses are a special lenses that change brightness in response to the strength of sunlight. These lightly tinted lenses darken under strong sunlight, with their tint darkening to the maximum degree as the sunlight strengthens and lightening as it weakens. Since the color of the lens itself changes with the brightness of the field of view, they can be used under a wide range of conditions. In addition, Yamamoto Kogaku’s photochromatic lenses are distinguished by their rapid speed of adjustment. However, since photochromatic lenses tend to become less effective as they age, starting to become less responsive and to show less change in tint after two to three years, we recommend storing them in a dark place under room temperature to extend their usefulness.

Anti-fogging technologies to maintain clear fields of view

Fog resistance

Our strongest anti-fogging treatment Our Premium Anti-Fog coating boasts even stronger fog resistance than our standard anti-fogging coating. Even though the principles of anti-fogging treatments used vary by field—for example, hydrophilic anti-fogging technologies are used in swimming goggles while water-absorbing anti-fogging technologies are used in snow goggles—our recent R&D initiatives have succeeded in tripling the anti-fogging performance of swimming goggles and doubling it in snow goggles.

Snow goggles

These lenses are equipped with special filtering functions that effectively block out glare in the vision due to diffuse reflection of light from the sun and other sources. Specifically, they enable a clear view of unevenness in the road by restraining glare from the road’s surface, make it possible to see inside buildings and other structures by reducing diffuse reflection of light on windows, and make it possible to see fish and underwater features by reducing glare from the water’s surface.
In addition, unlike low-priced polarizing lenses, which are susceptible to water damage and lack durability, Yamamoto Kogaku’s polarizing lenses have the durability needed for use in a wide range of outdoor recreation environments (including uses in extreme temperature and humidity and underwater).

Double water absorption capacity than ever !

Swimming goggles

Four times the durability

The hydrophilic ingredients used in the anti-fogging coating on our swimming goggle lenses reduce soiling due to swimming pool water and peeling due to rubbing under repeated (normal) use.

(compared to our other products)

Premium Anti-Fog successfully increases durability fourfold by increasing the volume of these hydrophilic ingredients used.

Peeling is a common issue in standard vapor-deposition mirror coating, the final stage of the lens process. However, our mirror technology eliminates this worry by sealing the mirror layer inside the lens. Furthermore, since this technology involves use of a uniform mirror layer formed in advance, it eliminates the issues of color spotting and differences in coloration in the field of view.
In addition, since the lenses of safety glasses and snow goggles have a petroid coating on the outermost layer, they result in mirror lenses with strong scratch resistance.

Scratch- and shock-resistance

These special surface coatings were developed to demonstrate high water repellency to eliminate adherence of water droplets and snow while running or skiing. Since the ability to repel water and snow also repels dirt, they are resistant to dust and fingerprints as well. In addition, any dirt on the lens can be wiped away easily.

Design philosophy

SWANS products are basically designed to protect the safety and health of the wearer from the brand establishment. At the same time, our products must appeal to the users beyond being mere safety tools, that is to say, they should also bring out the best performance while fitting comfortably. As products to be worn on the face, they inevitably showcase the individuality of the wearer. We constantly work to match style with function.

Designs that are safe for the wearers and others around them

At the heart of the SWANS and YAMAMOTO brands is the spirit of developing protective gear cultivated over 105 years of being in business since 1911. We question and investigate whether sufficient strength and safety are guaranteed to protect the eyes and other body parts, as well as possibilities of the protective gear hurting the wearer or other nearby athletes. All products under the SWANS brand are manufactured with the highest safety standards.

Making products, wearers, and vision more beautiful

We interpret “beauty” in many ways. First, a product must be appealing, simply having an aesthetic shape and form. Additionally, it should support the performance of the wearer, helping to create moments of poignancy and healthy beauty. The beauty of a product is perfected by overlapping with the moment of the wearer’s activity. As an optics manufacturer, we pursue the highest quality and precision in lens performance, meeting the demanding requirements of critical environments in the sports world and industrial safety.

Fitting the body and fitting in with the environment, with style

The required functions, fit, and style depend on the use conditions, environment, and sports event. Our designs deliver solutions on the back of our expertise, built up through our continuing R&D with athletes. We will keep exploring what we can do for the conservation of nature.

Identifying possible issues and concentrating on the essentials
