[Brand introduction]
The SWANS is a domestic brand created by Yamamoto Opticals, Inc. founded in 1911. Based on Japanese head data, this product is designed to fit Japanese people and control the light that has been cultivated in over 100 years of history, and is supported by many top athletes both domestic and abroad.

What is visible light transmittance?
This is a numerical value of the amount of light that the lens can pass through. The state of the naked eye is displayed as 100% as 0% to 100%. The lower the numeric means that the lens is impervious to light (darker)

What is polycarbonate?
Polycarbonate used for SWANS sunglasses is a resin with excellent impact resistance and transparency, and is also used for airplane windshield and space helmet applications. Because it is shock-resistant, it wont break easily, even if it is broken, making it a highly safe material for sports sunglasses lenses. SWANS uses the unique scratch-resistant lens "Petroid Lenses" based on this polycarbonate.

What is polarized lenses?
The polarizing function effectively cuts out irregular light rays (polarized) from various objects such as roads, water, windows, cars, buildings, and more. The lenses cut out light in the way so you can see the scenery clearly and you wont feel tired even after long periods of use.
