The Ray-Ban RB4323 sunglasses bring a fresh take on the brand's iconic square frame heritage. Built from lightweight acetate with a full-rim construction, these unisex frames deliver all-day comfort in a slim, modern profile that works equally well for men and women.
Contemporary Design Meets Classic Ray-Ban DNA
The RB4323 features a clean square shape (51mm lens width, 20mm bridge, 150mm temples) that flatters round and oval face shapes by adding definition and structure. The acetate frame construction keeps weight down while offering durability you can count on. Ray-Ban offers the 4323 in nine distinct options—from classic black and Havana tortoise to on-trend transparent grey and clear gradient styles that reflect current eyewear trends. Gradient lenses are carefully matched tone-on-tone with frame colors, and polarized options are available for glare reduction.
The straight temples and saddle bridge design ensure a secure, balanced fit without pressure points. These frames are prescription-ready, making them a practical choice whether you need vision correction or prefer them as sunglasses. The 4323 sits comfortably between Ray-Ban's heritage Wayfarer styles and newer minimalist designs—recognizable but not retro, streamlined but not stark.
Built for Real Life
Acetate frames blend flexibility with strength, resisting everyday wear better than cheaper plastics. The full-rim design supports prescription lenses well, including higher prescriptions that benefit from the coverage a full rim provides. At 51mm, the lens width suits small to medium faces, and the 20mm bridge offers a standard fit for most nose shapes.
Each pair includes 100% UV protection to shield your eyes from harmful rays. The lightweight build means you can wear them from morning commutes to evening outings without fatigue. Whether you're drawn to the understated elegance of transparent grey or the warmth of Havana brown, the RB4323 delivers versatile style that adapts to your wardrobe.

Frequently Asked Questions
Are Ray-Ban 4323 sunglasses prescription-ready?
Yes, the Ray-Ban RB4323 frames are fully prescription-ready. The full-rim acetate construction supports single-vision, bifocal, and progressive lenses. The 51mm lens width and full-rim design work well for a wide range of prescriptions, and the frames can accommodate both standard and high-index lenses for stronger prescriptions.
What face shapes do Ray-Ban 4323 sunglasses fit best?
The Ray-Ban 4323's square shape works best for round and oval face shapes, where the angular lines add definition and balance. The 51mm lens width and clean square profile create a flattering contrast to softer facial features. The unisex design suits both men and women with small to medium face sizes.
What size are Ray-Ban 4323 frames?
The Ray-Ban RB4323 measures 51mm lens width, 20mm bridge width, and 150mm temple length (51-20-150). The lens height is approximately 42mm. This is considered a small to medium size frame, suitable for most adults. The 133mm frame width (hinge to hinge) provides a comfortable fit without being oversized.
Are Ray-Ban 4323 sunglasses polarized?
The Ray-Ban 4323 is available in both polarized and non-polarized lens options. Polarized versions (such as 601/9A and 710/83) reduce glare from reflective surfaces like water, snow, and pavement, making them ideal for driving and outdoor activities. Non-polarized gradient options are also available for everyday wear.
What material are Ray-Ban 4323 frames made from?
The Ray-Ban RB4323 frames are made from acetate (also called cellulose acetate), a premium plastic material known for its durability, lightweight comfort, and ability to hold rich colors and patterns. Acetate is more flexible and hypoallergenic than standard plastic, and it's the same material used in many high-end eyewear frames.
How do Ray-Ban 4323 compare to the New Wayfarer 2132?
The Ray-Ban 4323 offers a slimmer, more modern profile compared to the New Wayfarer 2132. Both are square acetate frames, but the 4323 features straighter temples, a lighter build, and contemporary transparent color options. The 2132 has a slightly more retro look with visible rivets and a boxier shape, while the 4323 leans minimalist and streamlined.

Ray-Ban 4323 vs New Wayfarer 2132 vs Justin 4165
Choosing between Ray-Ban's square acetate frames comes down to your style preference and fit needs. The RB4323 sits in the sweet spot between heritage and modern design.
Ray-Ban 4323: If you want a contemporary, streamlined square frame with transparent color options and a lightweight feel, the 4323 is your best choice. It's the most modern-looking of the three, with clean lines, straight temples, and a slim profile. The 51mm size works well for small to medium faces, and the variety of gradient and transparent options reflects current eyewear trends. Starting at $125.09, it's priced between the Justin and the New Wayfarer.
Ray-Ban New Wayfarer 2132: The 2132 is the classic choice—iconic rivets, proven styling, and that unmistakable Wayfarer DNA. It's slightly boxier and more retro than the 4323, and it comes in more size options (50mm, 52mm, 55mm). If you want the frame that's been worn by celebrities for decades and prefer a heritage look, the New Wayfarer is hard to beat. It starts at $117.56, making it the most affordable option.
Ray-Ban Justin 4165: The Justin offers a larger 54mm fit with a rubberized matte finish that feels sporty and casual. It's great for bigger faces or anyone who wants a more laid-back vibe. Starting at just $98.00, it's the budget-friendly pick, though the matte finish can show wear over time and it lacks the refined transparent options of the 4323.
Our recommendation: Choose the RB4323 if you value modern aesthetics, lightweight comfort, and on-trend transparent or gradient styles. It's the most versatile for both casual and dressier looks, and the prescription-ready construction makes it practical for everyday wear. The 2132 is better for purists who want the classic Wayfarer look, while the Justin suits those prioritizing size and affordability.
