The Maui Jim KAHUNA MJ162 sunglasses in Gunmetal with Neutral Grey lenses represent one of the brand’s most enduring designs—a bestseller for over 15 years that continues to earn loyalty from pilots, anglers, and outdoor enthusiasts who demand optical excellence. Named after the Hawaiian word for master craftsman, these rectangular polarized sunglasses combine refined metal construction with Maui Jim’s legendary PolarizedPlus2 lens technology.
What sets the KAHUNA apart isn’t the frame—it’s the glass. Maui Jim’s proprietary PolarizedPlus2 lenses eliminate 99.9% of glare through three layers of polarization while doing something ordinary polarized sunglasses can’t: they enhance color. A patented blend of rare earth elements boosts reds, greens, and blues, delivering richer contrast and depth perception without the flat, washed-out view of standard dark lenses. The Neutral Grey lens option offers the highest available light reduction for bright, direct sunlight while maintaining true color perception—ideal for driving, water sports, and high-glare environments.
The lenses are SuperThin Glass, 20-32% thinner and lighter than standard glass, offering the crispest optics available with superior scratch resistance. Every lens includes anti-reflective coating on the back surface to eliminate bounce-back glare, plus oleophobic treatment that repels water, oil, and sunscreen. All Maui Jim lenses block 100% of UVA and UVB rays and filter harmful high-energy visible (HEV) blue light.
The KAHUNA features a double-bridge metal frame in gunmetal finish with a saddle-style crossbar that distributes weight evenly. Silicone nose pads prevent slipping, and anti-corrosive spring hinges flex to accommodate different face shapes and sizes. Reviewers consistently note the fit works well for average to wide faces—one long-time owner noted the frames “fit my head perfectly (and I have a large head).”
“My Kahunas just turned 7 years old and look brand new. I wear them almost everyday.” — Zappos customer review
The rectangular shape (61mm lens width, 18mm bridge, 130mm temple) offers excellent coverage without the bulk of wraparound styles. The frames are made in Japan and designed for saltwater environments—corrosion-resistant and built to handle fishing, boating, and beach conditions.
The KAHUNA is available with prescription lenses through Maui Jim’s MauiPassport program, which uses digital surfacing technology to maintain the PolarizedPlus2 benefits in single vision or progressive prescriptions. Prescription options include Maui Brilliant (lightest weight), Maui Evolution (high-index for stronger Rx), and polycarbonate materials.
Measurements: 61-18-130mm (lens width-bridge-temple). Full-rim metal construction. Unisex fit. Includes Maui Jim case and cleaning cloth.
