The Ray-Ban RB4392D sunglasses bring a bold square silhouette to the brand's low bridge fit collection. Built with a full-rim injected acetate frame, these unisex shades measure 66mm across the lens with a 17mm bridge and 145mm temples—proportions that deliver generous coverage without overwhelming your face. The signature Ray-Ban logo sits cleanly on each temple, and the iconic metal rivet detail anchors the front corners.
Low Bridge Fit for All-Day Comfort
The RB4392D is engineered for low bridge fit, making it a strong choice if standard frames tend to slide down your nose, sit too low, or press uncomfortably on your temples or cheeks. The modified nose bridge and adjusted frame angles distribute weight more evenly across flatter nose profiles—a fit refinement that's often hard to find in square acetate styles. Customers report the difference is immediate: no more constant adjusting, and the lenses stay positioned where they should.
Prescription-Ready & UV Protection
These frames are prescription-ready, so you can add single-vision, progressive, or polarized Rx lenses to match your needs. The stock lenses offer 100% UV protection, shielding your eyes from harmful UVA and UVB rays. Available in six color combinations—from classic black with dark grey or blue lenses to transparent grey frames—the RB4392D adapts to your style while keeping the clean, modern square shape front and center. It's a versatile frame that works equally well for daily wear, driving, or weekend adventures.

Frequently Asked Questions
What does the 'D' mean in Ray-Ban RB4392D?
The 'D' designation indicates this is a low bridge fit model, specifically designed for Asian fit or anyone with a flatter nose bridge. Low bridge fit frames feature modified nose pads and frame angles to prevent the glasses from sliding down your nose or sitting too low on your face, providing a more comfortable and secure fit.
Are Ray-Ban 4392D sunglasses prescription-ready?
Yes, the Ray-Ban RB4392D frames are prescription-ready and can accommodate single-vision, progressive, or polarized prescription lenses. The full-rim injected acetate construction provides a stable base for prescription lens installation, making them suitable for those who need corrective eyewear.
What is the size of Ray-Ban 4392D sunglasses?
The Ray-Ban RB4392D measures 66mm lens width, 17mm bridge width, and 145mm temple length (66-17-145). The lens height is approximately 51mm. This is considered a wide fit with generous coverage, making it suitable for medium to large faces and those who prefer oversized square frames.
How does the Ray-Ban 4392D compare to the New Wayfarer?
The RB4392D is a larger, more modern square frame with low bridge fit, while the New Wayfarer (RB2132) is smaller with a more classic trapezoidal shape and standard fit. The 4392D has a 66mm lens versus the New Wayfarer's 52-58mm options, and the 4392D's injected construction makes it lighter than the New Wayfarer's acetate build.
What face shapes work best with Ray-Ban 4392D?
The square shape of the RB4392D works best for oval and round face shapes, as the angular lines add definition and contrast. The generous 66mm lens width and low bridge fit design also make it ideal for those with wider faces or flatter nose bridges who need extra coverage and a secure fit.
Do Ray-Ban 4392D sunglasses come with polarized lenses?
The Ray-Ban RB4392D is available in both polarized and non-polarized lens options. Polarized versions (indicated by color codes ending in 9A or 81) reduce glare and enhance clarity, making them ideal for driving or water activities. Non-polarized versions offer standard UV protection at a lower price point.

Ray-Ban 4392D vs. Justin 4165 vs. New Wayfarer 2132
Choosing between Ray-Ban's square frames comes down to fit, size, and style. The RB4392D is purpose-built for low bridge fit with a generous 66mm lens, making it the best choice if standard frames slide down your nose or sit uncomfortably. The Justin 4165 shares a similar modern square aesthetic and size (54-58mm lens options), but uses a standard fit—great if you don't need the low bridge accommodation and want Ray-Ban's most popular contemporary square frame. The New Wayfarer 2132 is smaller (52-58mm) with a classic trapezoidal shape and more vintage appeal, ideal for those who want an iconic look in a compact package.
If you have a flatter nose bridge or Asian fit needs, the 4392D is your frame—it's specifically engineered to stay in place and distribute weight evenly. If you prefer a standard fit and want the most versatile modern square, go with the Justin. And if you're after Ray-Ban heritage in a smaller, more retro silhouette, the New Wayfarer is the classic choice. All three are prescription-ready and offer excellent UV protection, so your decision hinges on fit and aesthetic preference.
