DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Maui Jim OHAI MJ334 Sunglasses deliver the minimalist look of rimless eyewear in a large fit that's hard to find. Named after the Hawaiian ohai tree known for its wide, sheltering canopy, these sunglasses offer generous coverage without the weight—a rare combination for anyone who's struggled to find rimless frames that actually fit a bigger head.

MauiBrilliant Lenses: Near-Glass Clarity at One-Third the Weight

The OHAI comes equipped with MauiBrilliant lens material, Maui Jim's most advanced non-glass optic. These lenses deliver optical clarity nearly identical to SuperThin Glass—with an Abbe value of 56 compared to glass's 59—but weigh just one-third as much. That's a significant difference when you're wearing sunglasses all day. The lenses also feature Maui Jim's patented PolarizedPlus2 technology, which eliminates 99.9% of glare and enhances color through a blend of three rare-earth elements that boost reds, greens, and blues. Every pair blocks 100% of UV rays and harmful high-energy visible (HEV) blue light, plus includes anti-reflective, scratch-resistant, and oleophobic coatings that repel water, oil, and smudges.

MauiFlex Frame: Memory Metal That Molds to Your Head

The frame is constructed from MauiFlex, a proprietary memory metal that adapts to your unique head shape and holds that fit over time. Despite being incredibly lightweight and flexible, MauiFlex is highly durable. The rectangular lenses (59.5mm wide) are mounted via a single bridge with adjustable silicone nose pads, and the temples feature rubberized tips for a secure, non-slip grip. Reviewers note the OHAI stays put during active use—hiking, jogging, or time on the water—thanks to these thoughtful details. The base curve is 6, which provides adequate wrap without the temple pinching that some wearers experience with higher-curve sport frames.

Who It's For

This is an extra-large frame (142mm frame width) designed for larger faces and heads. Most of Maui Jim's rimless models run medium to medium-large, so the OHAI fills a real gap in the lineup. The oval rimless shape complements medium square, oval, and heart-shaped faces. It's available in prescription and works well for everyday wear, driving, and outdoor activities where you want an unobstructed field of view. Measurements: 59.5mm lens width, 18mm bridge, 140mm temple length.

Frequently Asked Questions

Are the Maui Jim OHAI sunglasses available with prescription lenses?

Yes, the OHAI MJ334 is available with prescription lenses in both single vision and progressive options. The MauiBrilliant lens material used in the OHAI is specifically designed to be prescription-ready and is Maui Jim's most popular choice for Rx sunglasses. Contact our licensed opticians to discuss your prescription needs and lens options.

What is MauiBrilliant lens material and how does it compare to glass?

MauiBrilliant is Maui Jim's most advanced lens material, offering optics nearly as clear as glass (Abbe value of 56 vs. glass's 59) with just one-third the weight. It provides better impact resistance than glass, excellent scratch resistance, and is lighter than polycarbonate while delivering almost double the clarity of traditional polycarbonate lenses. It's ideal for all-day wear and active use.

What size head do the OHAI sunglasses fit?

The OHAI MJ334 is designed as a large-fit frame with a 142mm frame width, specifically made for people with bigger heads or wider faces. Most of Maui Jim's rimless options run medium to medium-large, so the OHAI was created to fill the need for an extra-large rimless option. The MauiFlex memory metal frame molds to your head shape for a customized, comfortable fit.

What is MauiFlex frame material?

MauiFlex is Maui Jim's proprietary memory metal that molds to the wearer's head shape and remembers that fit longer than traditional metal frames. Despite being incredibly lightweight and flexible, MauiFlex is highly durable and made to last. The material allows the OHAI to maintain its shape while providing all-day comfort.

Are rimless sunglasses durable enough for active use?

Yes, the OHAI features rubberized temple tips and silicone non-slip nose pads that keep the frame securely in place during hiking, jogging, or water activities. The MauiFlex metal construction is highly durable, and the MauiBrilliant lenses offer excellent impact and scratch resistance. While rimless frames require reasonable care, the OHAI is built for an active lifestyle.

What face shapes work best with the OHAI sunglasses?

The OHAI's oval rimless frame style complements medium square, oval, and heart-shaped faces. The rectangular lens shape with clean lines provides a versatile look that works for both men and women. The adjustable nose pads allow for fine-tuning the fit to match your specific facial contours.

Maui Jim OHAI vs. Similar Rimless Sunglasses

The OHAI MJ334 sits at the top of Maui Jim's rimless collection as the extra-large option, but how does it compare to other popular models in our catalog?

OHAI vs. Banyans MJ412

Both the OHAI and Banyans are designed for larger faces, but they take different approaches. The Banyans features a Grilamid frame material that's extremely durable and bendable, with a slightly wider frame (around 145mm) for very wide faces. However, the OHAI's MauiFlex memory metal is lighter and more flexible, molding to your head shape over time. The OHAI also comes standard with MauiBrilliant lenses—Maui Jim's most advanced lens material—while the Banyans typically uses MauiPure. If you prioritize the lightest weight and best optical clarity, the OHAI is worth the extra investment ($234.69–$260.77 vs. $191.54–$222.31). If you need the absolute widest fit and prefer a more impact-resistant Grilamid frame, the Banyans is your choice.

OHAI vs. Ho'okipa MJ407

The Ho'okipa is the model that started Maui Jim's rimless legacy, and it remains a customer favorite. It's a medium-to-large fit (134mm frame width) that works well for average-sized heads, and it's more affordable at $167.78–$180.56. However, if you've tried the Ho'okipa and found it too small, the OHAI is the natural upgrade. The OHAI offers a larger lens (59.5mm vs. the Ho'okipa's smaller coverage), a fully rimless design (the Ho'okipa is semi-rimless), and the advanced MauiFlex frame that adapts to your head. The Ho'okipa is a great entry point, but the OHAI is purpose-built for people who need more room.

OHAI vs. Lighthouse MJ423

The Lighthouse is another fully rimless option at a lower price ($153.08–$184.75), but it's a smaller fit that won't work for larger heads. The Lighthouse is ideal if you have a medium-sized face and want a minimalist rimless look without the extra coverage. The OHAI, by contrast, is specifically engineered for people who need an extra-large fit and maximum lens coverage. If you've struggled to find rimless sunglasses that fit comfortably, the OHAI's 142mm frame width and MauiFlex construction make it the clear winner.

Bottom line: The OHAI MJ334 is the best choice if you need a large-fit rimless sunglass with the lightest weight, best optical clarity, and a frame that molds to your head. It's a premium option, but the MauiBrilliant lenses and MauiFlex frame justify the investment for all-day comfort and performance.
