The Ray-Ban RB4428 sunglasses bring a fresh take on square frames with bold, structured lines and a contemporary edge. Built from durable acetate, these unisex frames fit medium-to-large faces for daily wear.
Modern Square Design That Works
The RB4428 features a clean square shape with thick, full-rim construction and tapered temples. The 56mm lens width and high bridge fit (21mm) make these frames ideal for medium to larger faces or anyone who prefers extra coverage. Unlike the slimmer New Wayfarer, the 4428 has a bolder presence—more substantial without feeling heavy. The square geometry adds structure and definition, making them particularly flattering on round or oval face shapes.
Available in six colors—including classic black with green lenses (601/31) and tortoise with blue lenses (710/R5). Polarized options are available in select finishes, cutting glare and improving contrast for driving or water activities.
Acetate Frames: Lightweight and Built to Last
Ray-Ban constructs the RB4428 from cellulose acetate, a premium plastic that's lightweight, durable, and holds color well. The material resists deformation and maintains its shape over time. The temples feature metal cores for easy adjustment, and the frames are hand-finished for a smooth surface. These frames are prescription-ready, so you can add your Rx lenses without compromising style or fit.
The lenses provide 100% UVA and UVB protection, shielding your eyes from harmful rays whether you're commuting, traveling, or spending the day outdoors. Ray-Ban's signature logo is etched on the right lens and embossed on the temples.

Frequently Asked Questions
Are Ray-Ban RB4428 sunglasses prescription-ready?
Yes, the Ray-Ban RB4428 sunglasses are fully prescription-ready. The frames can accommodate single vision, progressive, and bifocal lenses. Ray-Ban uses Digital Surface Technology to optimize prescription lenses for their frames, ensuring clear vision at all angles. You can order them with your prescription through Designer Optics.
What is the frame size of the Ray-Ban 4428?
The Ray-Ban RB4428 measures 56mm lens width, 21mm bridge width, and 145mm temple length (56-21-145). This is considered a medium to large fit. The high bridge design (21mm) provides extra clearance and comfort for those with higher nose bridges or anyone seeking more coverage.
What material are Ray-Ban 4428 frames made from?
The RB4428 frames are made from cellulose propionate, a premium plastic material that's lightweight, flexible, and hypoallergenic. Propionate has lower density than acetate, making it stronger and more resistant to deformation while remaining comfortable for all-day wear. The temples contain metal cores for easy adjustment.
Do Ray-Ban 4428 sunglasses have UV protection?
Yes, all Ray-Ban RB4428 sunglasses provide 100% UVA and UVB protection, blocking harmful ultraviolet rays. Polarized versions are also available in select colors, which eliminate glare and enhance contrast—particularly useful for driving, water sports, and bright outdoor conditions.
What face shapes work best with Ray-Ban 4428 square frames?
The Ray-Ban RB4428's square shape works best for round and oval face shapes, as the angular lines provide contrast and add definition. The frames can also suit heart-shaped faces. Those with square faces may prefer rounder styles like the Erika or Aviator to soften angular features, though personal preference always matters most.
How does the Ray-Ban 4428 compare to the New Wayfarer?
The RB4428 has a more contemporary, streamlined square shape compared to the New Wayfarer's classic trapezoid design. The 4428 features a high bridge fit (21mm vs. 18mm on most Wayfarers) and bolder, thicker frames. Both are made from lightweight materials and are prescription-ready, but the 4428 offers a more modern, structured aesthetic with cleaner lines.

Ray-Ban 4428 vs. New Wayfarer 2132 vs. Justin 4165
Choosing between the Ray-Ban RB4428, New Wayfarer RB2132, and Justin RB4165 comes down to fit, style preference, and how you plan to wear them.
The RB4428 is the most contemporary of the three, with bold square lines, a high bridge fit (21mm), and a structured, modern aesthetic. It's ideal if you want a fresh take on square frames with extra nose clearance and a confident, clean look. The 56mm lens provides solid coverage without feeling oversized.
The New Wayfarer RB2132 is the classic choice. Its trapezoid shape and cultural legacy make it instantly recognizable—think James Dean, Bob Dylan, and decades of pop culture. It's available in more size options (52mm, 55mm, 58mm) and has a softer, more retro vibe. The standard 18mm bridge works for most, but if you need higher clearance, the RB4428 is the better pick.
The Justin RB4165 offers a relaxed, casual alternative with a slightly larger 54mm lens and a more laid-back feel. It's great for everyday wear and outdoor activities, but it lacks the structured precision of the RB4428. The Justin's rubber finish options add texture, while the RB4428's polished propionate feels more refined.
Our recommendation: If you have a higher nose bridge or prefer a bold, modern square frame, the RB4428 is your best bet. If you want the iconic Wayfarer heritage and multiple size options, go with the RB2132. And if you're after a casual, easygoing vibe with a larger fit, the Justin RB4165 delivers.
