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 lens
Lenses can be easily replaced by opening and closing the parts on the side of the frame. It locks when worn, making it resistant to impact.

Adjustable temple
By bending the temple ends inward, you can make fine adjustments to match the shape of your head.
Note: Only the rubber grip section is adjustable. Please do not apply excessive force to the temples, as this may cause damage or breakage.

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.
