DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Maui Jim KIOPA'A MJ671 sunglasses bring a modern cat-eye silhouette to one of the most respected names in polarized eyewear. Designed with SuperThin Glass lenses and the brand's patented PolarizedPlus2 technology, these frames deliver the optical clarity Maui Jim built its reputation on—now in a shape that flatters round, oval, and heart-shaped faces with equal ease.

PolarizedPlus2 Technology: More Than Polarization

Maui Jim started in 1987 on Ka'anapali beach in Lahaina, Maui, selling sunglasses that could handle the island's intense glare and UV exposure. That need drove the development of PolarizedPlus2, a lens technology that goes beyond simple polarization. The lenses eliminate 99.9% of glare and block 100% of harmful UVA and UVB rays, but the real difference is in color. Maui Jim infuses each lens with a patented blend of three rare earth elements that enhance reds, greens, and blues, so the world looks more vivid—not just darker. Anti-reflective coatings on both sides of the lens eliminate bounce-back glare, and an oleophobic treatment sheds water, sunscreen, and smudges.

SuperThin Glass: The Clearest View Available

The KIOPA'A is built with SuperThin Glass, Maui Jim's premium lens material. It's 32% thinner and lighter than standard glass, which means less weight on your nose and temples, but it still delivers the absolute crispest optics the brand offers. Glass resists scratches better than any polymer, so these lenses stay clear season after season. Available lens colors include Neutral Grey for bright, direct sunlight; HCL Bronze for everyday variable conditions with a warm tint and excellent contrast; and Maui Rose, which offers the highest contrast available and works beautifully for fast-moving activities.

Cat-Eye Shape, Medium Fit

The frame measures 54mm lens width, 19mm bridge, and 140mm temples—a medium fit that works for most face widths. The cat-eye shape adds definition to round faces, complements the natural angles of oval and heart-shaped faces, and draws attention upward to the eyes and cheekbones. The nylon frame is lightweight and durable, with Maui Jim's signature script logo on the temples and the brand's wavy pattern on the temple tips. Spring hinges provide flex and a secure, comfortable fit. The frame is available in four finishes: Shiny Black with Neutral Grey lenses, Matte Cyclamen (pink) with HCL Bronze, Matte Dark Havana tortoise with HCL Bronze, and Shiny Transparent Pink with Maui Rose lenses.

These sunglasses are prescription-ready. Maui Jim cat-eye frames can be fitted with single-vision or progressive prescription lenses—check with your eye care professional for compatibility and lens material options.

Frequently Asked Questions

Are Maui Jim KIOPA'A sunglasses prescription-ready?

Yes, the KIOPA'A MJ671 can be fitted with prescription lenses. Maui Jim cat-eye sunglasses are available in both single-vision and progressive prescriptions. Because the KIOPA'A features SuperThin Glass in its non-prescription form, you'll want to consult with your eye care professional about the best prescription lens material for your needs—MauiBrilliant is typically the prescription-compatible option that comes closest to glass clarity.

What is SuperThin Glass and how does it compare to MauiPure?

SuperThin Glass provides the absolute crispest optics available from Maui Jim—32% thinner and lighter than standard glass with the best scratch resistance. MauiPure is the brand's most popular lens material and offers optics almost as crisp as SuperThin Glass but with even lighter weight and excellent shatter resistance. SuperThin Glass is ideal if optical clarity is your top priority; MauiPure is a great all-around choice for active lifestyles.

What face shapes look best in cat-eye sunglasses?

Cat-eye sunglasses are particularly flattering for round, oval, and heart-shaped faces. The angular edges and upswept corners add definition to round faces, complement the natural balance of oval faces, and mirror the combination of curves and angles in heart-shaped faces. The KIOPA'A's medium fit (54mm lens width) works well for most face sizes.

What is Maui Jim PolarizedPlus2 technology?

PolarizedPlus2 is Maui Jim's patented lens technology that eliminates 99.9% of glare and blocks 100% of UVA and UVB rays. What sets it apart is a blend of three rare earth elements infused into the lens that enhance red, green, and blue wavelengths, revealing more vivid colors and detail. Every lens also includes anti-reflective coatings on both sides and an oleophobic treatment that repels water and oil.

Which lens color should I choose for the KIOPA'A?

Neutral Grey offers the highest light reduction and richest colors, best for bright, direct sunlight. HCL Bronze (High Contrast Lens) provides a warm tint with excellent contrast for everyday variable conditions, from full sun to overcast. Maui Rose offers the highest contrast available with a subtle rose tint, perfect for fast-moving sports and activities. Your choice depends on your primary use and light conditions.

How do I care for SuperThin Glass lenses?

SuperThin Glass is highly scratch-resistant, but you should still clean the lenses with a microfiber cloth and lens cleaner or mild soap and water. Avoid paper towels or clothing, which can trap particles that scratch over time. The oleophobic coating makes the lenses easier to clean by repelling water, sunscreen, and oils. Store your sunglasses in the included case when not in use to protect them from impact.

Maui Jim KIOPA'A vs. Other Cat-Eye Sunglasses

If you're drawn to the KIOPA'A's cat-eye shape and Maui Jim's legendary lens technology, you might also be considering a few other models in the brand's lineup. Here's how the KIOPA'A compares to three other popular Maui Jim cat-eye frames available at Designer Optics.

KIOPA'A MJ671 vs. HONI MJ758

The Honi MJ758 is one of Maui Jim's best-selling cat-eye frames, with a 4.7-star rating across major retailers. It features a slightly smaller 54mm lens width and is known for its vibrant sunset-inspired color schemes. The Honi is a great choice if you want a softer, more playful cat-eye look, and it's priced slightly lower at $204-$223. However, the KIOPA'A offers more lens color variety and the premium SuperThin Glass material, which delivers the crispest optics Maui Jim makes. If optical clarity is your priority, the KIOPA'A has the edge.

KIOPA'A MJ671 vs. ORCHID MJ735

The Orchid MJ735 is another cat-eye option in a similar price range ($200-$222). Both frames are prescription-compatible and feature PolarizedPlus2 lenses, but the aesthetic differs. The Orchid may have a more pronounced or subtle cat-eye sweep depending on the specific model variation, so your choice comes down to which silhouette you prefer. The KIOPA'A's SuperThin Glass lenses give it an advantage in scratch resistance and optical clarity, making it the better pick for those who prioritize long-term durability and the sharpest possible view.

KIOPA'A MJ671 vs. SANDY BEACH MJ408

The Sandy Beach MJ408 is a more budget-friendly cat-eye frame at $176-$179, making it an appealing option if you want Maui Jim's PolarizedPlus2 technology without the premium price. The trade-off is likely in the lens material—Sandy Beach typically features MauiPure lenses, which are lighter and more shatter-resistant than glass but don't quite match the optical crispness of SuperThin Glass. If you're active and want a lightweight, durable frame, Sandy Beach is a solid choice. If you want the absolute best clarity and scratch resistance, the KIOPA'A's SuperThin Glass is worth the investment.

Our recommendation: The KIOPA'A MJ671 is the best choice for customers who want Maui Jim's sharpest optics in a cat-eye frame. The SuperThin Glass lenses deliver unmatched clarity and scratch resistance, and the four color options let you match the frame to your style. If you're looking for a softer aesthetic or a lower price, the Honi and Sandy Beach are excellent alternatives—but for pure optical performance, the KIOPA'A stands out.
