The Maui Jim KOKI BEACH MJ433 Sunglasses deliver what customers call an almost weightless wearing experience, thanks to the brand’s lightest frame and lens combination. Named after Koki Beach—a hidden gem on Maui’s east shore along the Road to Hana, where pink-tinted sands meet dramatic red cliffs—these sunglasses bring that same vibrant, natural beauty to your view.
The KOKI BEACH features MauiPure lens material, Maui Jim’s most popular choice for good reason. These lenses combine optics almost as crisp as SuperThin Glass with ultra-lightweight construction and excellent scratch and shatter resistance. You get the visual clarity serious about sun protection demand, without the weight. The rounded rectangular shape fits medium faces comfortably, and the saddle-style bridge includes adjustable nose pads—a feature reviewers love for achieving a custom, no-slip fit that won’t dig into your cheeks or pull hair when you push them up on your head.
“They are so lightweight that I forget I’m wearing them.” — Zappos customer review
Every pair of KOKI BEACH sunglasses features Maui Jim’s patented PolarizedPlus2 lens technology, which goes far beyond basic polarization. The lenses eliminate 99.9% of glare and block 100% of harmful UVA and UVB rays, while a proprietary blend of three rare earth elements enhances red, green, and blue wavelengths. The result? Colors appear richer and more vibrant, contrast is sharper, and details pop—whether you’re driving, golfing, or spending long days outdoors. The lenses also include anti-reflective coating on the backside to eliminate bounce-back glare, plus oleophobic and hydrophobic treatments that repel water, oil, and smudges for easy cleaning.
The MJ433 is available in three distinctive colorways: Black and Grey Tortoise with Neutral Grey lenses (ideal for bright, direct sunlight), Purple Tortoise with Maui Rose lenses (offering the highest contrast for fast-action activities), and Olive Tortoise with HCL Bronze lenses (a warm, versatile tint perfect for everyday variable conditions). The full-rim injected nylon frame is both durable and flexible, designed for extended wear without fatigue.
Need prescription lenses? The KOKI BEACH is compatible with Maui Jim’s MauiPassport prescription program, available through authorized eye care professionals. You can add single vision or progressive lenses while retaining the full benefits of PolarizedPlus2 technology. Maui Jim sunglasses are recommended by the Skin Cancer Foundation as an effective UV filter for the eyes and surrounding skin, making them a smart choice for long-term eye health.
