CONTRAIM
Designed for competitive golfers, SWANS golf glasses offer the best field of vision in their history. From address to finish, the frame remains out of your field of vision throughout the swing, creating a state where "almost the entire field of vision is the lens." This reduces the stress of light and UV rays entering through gaps between your face and the sunglasses, allowing you to maintain concentration during play.
LENS TECH
Lens Color Features
The base smoke lens controls light evenly, providing a natural color tone of visibility and reducing eye fatigue even after long hours of use. Multi-coating (anti-reflection coating) on both sides of the lens reduces reflections and provides clear visibility. The visually stunning red shadow mirrors make it difficult to see the eye from the outside, thus making your concentration better.

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
Large molded flat lens
The absence of vertical curves suppresses distortion of the field of view. This achieves an unprecedentedly wide and optically superior field of view.

Nose parts that do not obstruct the view
By employing a slender yet robust titanium material, it achieves both high durability and safety. The nose piece does not obstruct your view when addressing the ball, such as when "looking towards the target" or "checking the ball and stance."

Ratchet mechanism that allows for angle adjustment
Equipped with a ratchet mechanism that allows for three-stage adjustment of the temple angle. This prevents uncomfortable situations such as gaps between the upper frame and the face, or interference between the cheeks and lenses, and ensures an optimal fit tailored to the wearer's face.

Non-Slip Rubber
Rubber inserts on the inner temples keep your eyewear securely in place, even during intense movement. The streamlined rubber design, flowing from the temple ends toward the lenses, embodies CONTRAIM’s commitment to precision and performance.
