PHOTOCHROMIC
Photochromic lenses automatically change their tint in response to UV (ultraviolet) light levels. They darkenoutdoors under high UV exposure to protect your eyes, and become lighter indoors, on cloudy days, in the shade, or at night to ensure clear vision.
*The lens color does not change inside a car with UV-cut window glasses.
The darkness of the lens color will change depending on conditions such as the amount of UV rays and temperature.
*The darkness of the lens color will gradually become less changeable as it deteriorates with years.
Photochromic lenses that change even at high temperatures
This lens addresses the issue of insufficient color development at high temperatures that plagued conventional photochromic lenses, ensuring rich color even in strong summer sunlight. It boasts highly practical and stable photochromic performance, taking into account various usage scenarios.
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
Non-slip Rubber Tips
The temple ends feature non-slip rubber that helps prevent the sunglasses from slipping during wear.
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.
