Produced by Professional Golfers Akie Iwai and Chisato Iwai
The sports-casual model "Radiant"—meaning "shining"—symbolizes the Iwai sisters, who continue to shine as professional golfers. It is packed with attention to detail, not only in its design but also in the temple construction, which ensures a comfortable fit that stays secure without slipping during swings.
LENS TECH
POLARIZED
It ensures clear vision by reducing glare caused by light reflected from water surfaces and roads.

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.

Lens Color Features
Polarized lenses that cut glare reflections from water, asphalt, grass, and other surfaces. Brown lenses combine the effect of blue light reduction with the natural color tone of the lens. This makes them an ideal color for long hours of use.

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
Design reflecting personality and passion
Chisato Iwai pursued a fashionable look. The shape features a teardrop design, and the front of the frame, including the lenses, is contoured to fit the face. By reducing the gap between the frame and the face, it effectively prevents strong sunlight and UV rays from entering.
