PETROID LENS
These lenses are made using advanced molding technology from polycarbonate resin, which is also used in bulletproof equipment and aircraft canopies, and are extremely transparent, impact-resistant, heat-resistant, and flame-retardant.
UV CUT LENS
All SWANS sunglasses lenses, regardless of lens color, block over 99.9% of ultraviolet (UV) rays. In addition, UV absorbers are incorporated into the lenses themselves, so performance does not deteriorate over time.
FRAME TECH
New lens shape for a closer fit
The updated lens shape minimizes the gap between the face and the lens, helping to suppress light intrusion and enhance focus during activity.
Under temple
By keeping the center of gravity low and keeping it in close contact with the face even around the cheeks and temples, it prevents shifting and shaking even when running with repeated up and down movements.
Non-slip rubber
Non-slip rubber to prevent displacement caused by up-and-down vibration during running has been applied to the inside of the temples, which contact the back of the head.
Adjustable nose pad
Adjustable to fit the wearer's nose shape. Made of rubber material that does not slip easily even when sweating.
