[Product introduction] A lightweight sports type with a slender frame that is strong against twisting and has an excellent grip. The front frame creates a fit and sporty feel, providing a moderate sense of hold. Although it is lightweight, it has a design that prevents it from slipping, making it ideal not only for sports but also for long-term use such as driving. [Brand introduction] SWANS is a domestic brand produced by Yamamoto Kogaku Co., Ltd., which was founded in 1911. Our products continue to be supported by many top athletes both in Japan and overseas due to product design tailored to Japanese people based on head data of Japanese people, and technology to control light cultivated over a history of over 100 years. ing. [Visible light transmittance] is the numerical value of the amount of light that passes through a lens. It is displayed from 0% to 100%, with the naked eye condition being 100%. The lower the number, the less light passes through (the darker) the lens. [What is polycarbonate] The polycarbonate used in SWANS sunglasses is a resin with excellent impact resistance and transparency, and is also used in aircraft windshields and space suit helmets. It is impact resistant and does not break easily, and even if it does break, it will not scatter, making it a highly safe lens material for sports sunglasses. SWANS uses a unique lens called "Petroid Lens" which is made of polycarbonate and is scratch resistant. [What is a polarized lens?] The polarizing function effectively cuts out diffusely reflected light (polarized light) from various objects such as roads, water, windows, cars, and buildings, reducing glare. This lens cuts out distracting light so you can see the scenery clearly, and you won't feel tired even when using it for long periods of time.
