DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Maui Jim KUNIAHI AF MJ688 sunglasses bring retro style and modern lens technology together in a rectangular frame designed specifically for Asian fit. With a 58mm lens width, 16mm bridge, and 145mm temples, these unisex sunglasses deliver both comfort and coverage for medium to larger face shapes.

PolarizedPlus2 Technology: Maui Jim's Signature Lens Innovation

Every pair of KUNIAHI sunglasses features Maui Jim's patented PolarizedPlus2 lens technology, which eliminates 99.9% of glare and blocks 100% of harmful UV rays. Unlike standard sunglasses that simply darken your view, PolarizedPlus2 lenses enhance the colors your eyes naturally perceive using three rare earth elements embedded in the lens. The result is vibrant, saturated colors with sharper contrast and improved depth perception—whether you're on the water, driving, or just enjoying a sunny day.

The KUNIAHI features MauiPure lens material, Maui Jim's most popular lens option. MauiPure combines optics almost as crisp as SuperThin Glass with ultra-lightweight construction and excellent scratch and shatter resistance. It's the sweet spot between optical clarity and durability, making these sunglasses ideal for everyday wear and active lifestyles.

"Absolutely love them, my new favorite pair of Maui's. Worth every penny and extremely lightweight." — Tommy Bahama customer review

Asian Fit Design for Superior Comfort

The "AF" in KUNIAHI AF stands for Asian Fit, which means these frames include a built-up nose bridge and adjusted temple angles for a more secure, comfortable fit. If you have a lower nose bridge or high cheekbones, or if standard sunglasses tend to slide down or sit too close to your face, the Asian Fit design solves those problems. Reviewers with larger head sizes specifically note that the KUNIAHI fits comfortably where other Maui Jim models felt too small, and the nearly 90-degree lens angle prevents the frames from sitting on your cheeks.

Retro Style, Modern Materials

The KUNIAHI's retro-inspired rectangular shape features a full-rim bio-nylon frame with an embossed vintage logo and traditional pin hinges. Available in four distinct colorways—Matte Transparent Grey, Matte Transparent Orange, Matte Transparent Blue, and Matte Black—each with carefully matched lens tints (Neutral Grey or Blue Hawaii). The transparent frame options with contrasting logo colors create what Maui Jim calls "a striking color juxtaposition" that stands out without being over the top.

These sunglasses are prescription-ready. Most Maui Jim frames can be fitted with prescription lenses through authorized retailers, so you can enjoy PolarizedPlus2 technology with your exact vision correction needs.

Made in Japan with Maui Jim's meticulous attention to detail, the KUNIAHI AF MJ688 delivers the clarity, vibrancy, and durability that have made Maui Jim the third-largest sunglass manufacturer in the world.

Frequently Asked Questions

What does AF mean in Maui Jim KUNIAHI AF MJ688?

AF stands for Asian Fit, which means these sunglasses feature a built-up nose bridge and adjusted temple angles designed for lower nose bridges and higher cheekbones. This design prevents the frames from sliding down or sitting too close to your face, providing a more comfortable and secure fit compared to standard frames.

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

MauiPure is Maui Jim's most popular lens material, combining optics almost as crisp as SuperThin Glass with ultra-lightweight construction and excellent scratch and shatter resistance. While glass lenses offer the absolute crispest optics and best scratch resistance, MauiPure provides nearly the same optical clarity at a fraction of the weight, making it ideal for all-day wear and active use.

Can I get prescription lenses in the Maui Jim KUNIAHI AF MJ688?

Yes, the KUNIAHI AF MJ688 is prescription-compatible. Most Maui Jim sunglasses can be fitted with prescription lenses (single vision or progressive) through authorized retailers. Prescription Maui Jim lenses maintain the PolarizedPlus2 technology, providing 100% UV protection, glare elimination, and color enhancement with your vision correction.

What is PolarizedPlus2 technology in Maui Jim sunglasses?

PolarizedPlus2 is Maui Jim's patented lens technology that eliminates 99.9% of glare, blocks 100% of UV radiation, and enhances color using three rare earth elements embedded in the lens. Unlike standard polarized lenses that just darken your view, PolarizedPlus2 enhances reds, greens, and blues for more vibrant, saturated colors with sharper contrast and improved depth perception.

What size face do the Maui Jim KUNIAHI AF MJ688 sunglasses fit?

The KUNIAHI AF features a 58mm lens width, 16mm bridge, and 145mm temples, making it suitable for medium to larger face shapes. Customer reviews specifically mention that these frames fit comfortably on larger head sizes (up to 7 5/8" fitted hat size) where other Maui Jim models felt too small, and the nearly 90-degree lens angle prevents them from sitting on your cheeks.

Are Maui Jim KUNIAHI sunglasses good for everyday wear?

Yes, the KUNIAHI AF is excellent for everyday wear. The lightweight MauiPure lenses and bio-nylon frame make them comfortable for extended use, while the PolarizedPlus2 technology provides superior glare reduction and color enhancement for driving, outdoor activities, and casual wear. The Neutral Grey lens option offers natural color perception ideal for varied, everyday conditions.

Maui Jim KUNIAHI AF vs. RED SANDS vs. 'AKAU: Which Rectangular Frame Is Right for You?

If you're drawn to Maui Jim's rectangular frames with PolarizedPlus2 technology, you have several excellent options. Here's how the KUNIAHI AF MJ688 compares to two popular alternatives in our collection.

KUNIAHI AF MJ688 vs. RED SANDS MJ432

Both the KUNIAHI AF and RED SANDS feature lightweight MauiPure lenses and rectangular styling, but they serve different needs. The RED SANDS is a proven bestseller with a slightly larger 59mm lens and more color options, making it ideal for those who want maximum coverage and variety. However, it's a standard fit frame that may slide down or sit too close to your face if you have a lower nose bridge.

The KUNIAHI AF solves this with its Asian Fit design—a built-up nose bridge and adjusted temple angles that provide a secure, comfortable fit for lower nose bridges and higher cheekbones. At $153 versus the Red Sands' $199-$239 price range, the KUNIAHI also offers better value. If fit has been an issue with standard frames, the KUNIAHI AF is your answer.

KUNIAHI AF MJ688 vs. 'AKAU MJ442

The 'AKAU MJ442 sits in the same price range as the KUNIAHI ($153-$161) and offers a similar rectangular shape with MauiPure lenses. The key difference is fit: the 'AKAU is standard fit only, while the KUNIAHI AF provides the Asian Fit advantage. Both deliver the same PolarizedPlus2 color enhancement and glare elimination, but if you need the specialized fit or prefer the KUNIAHI's retro-inspired aesthetic with embossed vintage logo, it's the better choice.

KUNIAHI AF MJ688 vs. ALENUIHAHA MJ839

The ALENUIHAHA MJ839 offers a modern square/rectangular unisex design at a higher price point ($201-$223). While it shares the PolarizedPlus2 technology and unisex appeal, it's a standard fit frame with a different design language. The KUNIAHI AF provides better value and the Asian Fit advantage, making it the smarter choice for those who need the specialized fit or prefer a more accessible price point.

Our recommendation: If you have a lower nose bridge, high cheekbones, or have struggled with standard sunglasses sliding down, the KUNIAHI AF MJ688 is specifically designed for you. Its Asian Fit construction, lightweight MauiPure lenses, and competitive pricing make it an outstanding choice. For those who don't need the Asian Fit and want a larger lens, the RED SANDS is worth the premium—but for most shoppers seeking comfort, value, and Maui Jim's legendary optics, the KUNIAHI AF delivers.
