LENS TECH

ULTRA LENS for FISHING Features

■ Clearer vision for more confident fishing
By enhancing visibility below the water’s surface, the lens makes underwater conditions easier to see, allowing for more precise lure control and better fishing performance.

■ Comfortable, stress-free wear all day
The lens density is designed to perform across a wide range of lighting conditions—from dawn to dusk, and from sun to shade. Paired with the frame design, it offers comfortable, all-day wear.

■ Polarized performance with high visibility
The polarized lens is especially effective in lightly green-tinted water conditions common in Japan, reducing surface glare while enhancing contrast. This makes lures and other artificial baits easier to see, improving overall visibility.

Lens Color Features

A lens is mainly targeted to sight fishing for bass. Lens color is easy to see the pale green water quality that is common in Japan. It doesn't feel dark even in dimly lit conditions in the morning or evening, or when throwing a lure into an obstacle in the shadow of a tree. The contrast is emphasized, making it easier to understand the underwater situation. Multi-coating (anti-reflection coating) inside of the lens reduces reflections and provides clear visibility.

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.

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 is teardrop, and the front part of the frame including the lenses is shaped to fit the face.
By reducing the gap between the front frame and the face, it effectively prevents strong sunlight and UV rays from intrusion.

Temple design compatible with caps and visors

The frame structure provides flexibility, enhancing overall fit and comfort.
The straighter temple shape compared to previous casual models also makes it easier to wear the glasses with a cap or visor. It provides a comfortable fit in any golf situation.

Adjustable nose pad

Adjustable to fit the wearer's nose shape.
Made of rubber material that does not slip easily even when sweating.
