STRIX D.A.
D.A. means Deperler (departure) and Arriver (arrival) in French. Ideal for stress-free use during long-term activities such as cycling and golf.
Flexible temples that wrap around your head with just the right amount of grip and lenses that can be replaced to suit the weather create a comfortable day.
LENS TECH
PHOTOCHROMIC
Photochromic lenses automatically change their tint in response to UV (ultraviolet) light levels. They darken outdoors 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.

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.
