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
Replaceable lenses to suit the weather and purpose
By locking firmly in the expanded state of the temples (when worn), we have created a structure that is resistant to shocks such as falling down from a bicycle or falling over.
Flexible temple
The flexible yet strong temples wrap around your head with just the right amount of holding power, creating a fit that doesn't put pressure on you but stays in place.
Adjustable nose pad
The adjustable nose pads can be gently narrowed or widened by hand to provide a customized fit for different nose widths. Please do not apply excessive force, as this may break the metal parts. For optimum optical performance, adjust the nose pads so that your eyes are positioned near the center of the lenses. The rubber nose pads provide a secure, non-slip fit, even during perspiration.
