DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Maui Jim KOKO HEAD MJ737 polarized sunglasses combine timeless style with cutting-edge lens technology. Named after the iconic O'ahu headland, these prescription-ready sunglasses feature a distinctive keyhole bridge and rounded square frame that flatters a wide range of face shapes. The lightweight full-rim construction ensures all-day comfort whether you're driving, at the beach, or exploring the city.

Every pair is equipped with Maui Jim's proprietary PolarizedPlus2® lens technology, which eliminates 99.9% of glare, blocks 100% of harmful UV rays, and enhances color vibrancy using rare earth elements. Available in two premium lens options—HCL Bronze for warm, high-contrast vision in variable light, and Neutral Grey for maximum protection in bright, direct sunlight—the KOKO HEAD delivers unmatched optical clarity. The matte finishes and skull temples with rubber grips provide secure, comfortable wear for extended periods.

Available in 48mm and 49mm lens widths, the KOKO HEAD accommodates single-vision, progressive, and bifocal prescription lenses, making it an ideal choice for those who need vision correction without compromising on premium polarized sun protection.

What lens technology is used in Maui Jim KOKO HEAD sunglasses?

The KOKO HEAD MJ737 features Maui Jim's proprietary PolarizedPlus2 lens technology, which eliminates 99.9% of glare, blocks 100% of harmful UV rays, and enhances color and contrast. This advanced polarization technology is built into the lens rather than applied as a coating, providing superior durability and optical clarity compared to standard polarized sunglasses.

What is Maui Jim PolarizedPlus2 lens technology?

PolarizedPlus2 is Maui Jim's proprietary lens technology that eliminates 99.9% of glare, blocks 100% of harmful UV radiation, and enhances color perception using a patented blend of rare earth elements. Unlike standard polarized lenses where polarization is applied as a coating, PolarizedPlus2 technology is built into the lens itself, providing superior durability, optical clarity, and vibrant color enhancement that makes reds, greens, and blues more vivid.

What size options are available for the Maui Jim KOKO HEAD MJ737?

The KOKO HEAD MJ737 is available in two lens widths: 48mm and 49mm. The 48mm size is offered in both Matte Tortoise with HCL Bronze lenses and Black Matte Rubber with Neutral Grey lenses, while the 49mm size comes in Matte Tortoise and Matte Black options. This range ensures a comfortable fit for various face sizes.

What's the difference between HCL Bronze and Neutral Grey lenses?

HCL Bronze (High Contrast Lens) offers a warm amber tint that enhances contrast and color vibrancy, making it ideal for variable light conditions from overcast to full sun. Neutral Grey is Maui Jim's darkest lens, providing maximum light reduction and true color perception, perfect for bright, direct sunlight and activities like boating or beach days. HCL Bronze is more versatile for everyday wear, while Neutral Grey excels in intense sun and high-glare environments.

Are Maui Jim KOKO HEAD sunglasses suitable for both men and women?

Yes, the Maui Jim KOKO HEAD MJ737 is designed as a unisex style suitable for all genders. The rounded square frame shape with keyhole bridge offers a versatile, classic aesthetic that complements various face shapes. The neutral colorways and medium sizing make these sunglasses an excellent choice for anyone seeking premium polarized eyewear.

What size options are available for the KOKO HEAD MJ737?

The KOKO HEAD MJ737 is available in two lens widths: 48mm and 49mm. The 48mm size is offered in Matte Tortoise with HCL Bronze lenses and Black Matte Rubber with Neutral Grey lenses.

Are the KOKO HEAD sunglasses suitable for both men and women?

Yes, the Maui Jim KOKO HEAD MJ737 is designed as a unisex style suitable for all genders. The rounded square frame shape with keyhole bridge offers a versatile, classic aesthetic that complements various face shapes. The neutral colorways (matte black, matte tortoise) and medium sizing make these sunglasses an excellent choice for anyone seeking premium polarized eyewear with timeless style.

What is the difference between HCL Bronze and Neutral Grey lenses?

HCL Bronze lenses offer high contrast and warm tones, making them ideal for variable light conditions and enhancing depth perception—perfect for driving and everyday use. Neutral Grey lenses provide the most natural color perception with minimal color distortion, making them excellent for bright, sunny conditions and water activities. Both options include full UV protection and polarization.

How durable are Maui Jim KOKO HEAD sunglasses?

The KOKO HEAD sunglasses are built for long-term durability with lightweight yet sturdy plastic frames and SuperThin Glass lenses that are 20-32% thinner than standard glass while offering superior scratch and solvent resistance. Customer reviews frequently mention pairs lasting 5-6 years with regular use. The frames feature Maui Jim's proprietary CLEARSHELL coating for enhanced durability, and the skull temples with rubber grips ensure secure, stable wear during active use.

What type of bridge does the KOKO HEAD MJ737 have?

The KOKO HEAD MJ737 features a keyhole bridge design, which sits higher on the nose and distributes weight more evenly than traditional saddle bridges. This classic bridge style reduces pressure points, prevents slipping, and provides enhanced comfort for extended wear. The keyhole bridge also adds a distinctive vintage-inspired aesthetic to the frame.

Product Comparison

Maui Jim KOKO HEAD vs LOCAL KINE vs HONI: Which Classic Maui Jim Is Right for You?

Choosing between Maui Jim's classic models comes down to your lifestyle and style preferences. All three feature the brand's legendary PolarizedPlus2® lens technology and prescription-ready frames, but each serves a distinct purpose.

KOKO HEAD MJ737: The Versatile Classic

The KOKO HEAD ($222.31–$249.16) strikes the perfect balance between timeless style and everyday versatility. Its distinctive keyhole bridge and rounded square shape deliver vintage-inspired charm that works equally well at the office, on the beach, or exploring the city. Customer reviews consistently praise its lightweight comfort and universal fit across face shapes. Choose the KOKO HEAD if you want one pair that does it all with sophisticated, understated style.

LOCAL KINE MJ810: The Performance Wrap

The LOCAL KINE ($200.08–$222.31) is purpose-built for water sports, fishing, and extended outdoor adventures. Its wrap design with thicker temples provides superior coverage and side protection, while rubber temple grips ensure the frames stay put during active use. Independent testing ranked it #2 out of 17 fishing sunglasses for optical clarity and fish-spotting ability. However, its sporty aesthetic is less versatile for casual or professional settings. Choose the LOCAL KINE if performance and maximum coverage are your priorities.

HONI MJ758: The Alternative Classic

The HONI ($222.31) offers a different take on classic styling at a competitive price point. While it shares the same PolarizedPlus2 technology and prescription compatibility as the KOKO HEAD, its frame geometry provides an alternative fit for those who find the keyhole bridge less comfortable. Choose the HONI if you want Maui Jim quality with a slightly different aesthetic, or if the KOKO HEAD's fit doesn't suit your face shape.

Our Recommendation

For most customers, the KOKO HEAD MJ737 represents the best all-around choice. Its iconic keyhole bridge design, versatile rounded square shape, and proven track record of customer satisfaction make it a timeless investment. The ability to choose between HCL Bronze (variable conditions) and Neutral Grey (bright sun) lenses adds further versatility. If you need maximum coverage for water sports, opt for the LOCAL KINE. If the KOKO HEAD's fit doesn't work for your face shape, the HONI provides an excellent alternative with identical lens technology.
