The Ray-Ban RB4387 sunglasses bring a fresh take on square frames with a clean, modern profile that works for daily wear. Built from lightweight acetate, these frames feature a keyhole bridge and gently squared lenses that sit comfortably between the vintage Wayfarer and the bolder Justin in Ray-Ban's lineup.
Design & Construction
The RB4387 uses a full-rim acetate frame in a 56mm lens width, 18mm bridge, and 145mm temples. The square shape flatters round and oval faces, while the keyhole bridge adds a retro detail without feeling dated. Many variants feature transparent fronts paired with solid-colored temples—a subtle two-tone look that's become popular in recent years. The sculpted nose pads and smooth temple tips help the frames stay put during all-day wear, though some wearers with lower nose bridges report occasional slipping.
Ray-Ban's logo is etched on the lens and embossed on the temples. The frames are prescription-ready, accepting single-vision, progressive, and polarized lenses. The polycarbonate lenses deliver 100% UVA and UVB protection and reduce glare, making them practical for driving and outdoor activities.
Who It's For
The RB4387 suits anyone looking for a versatile square frame that's less chunky than the Justin but more contemporary than the classic Wayfarer. The 56mm lens width fits most medium to large faces. The transparent and gradient options appeal to buyers who want something beyond basic black, while the classic 601/71 black frame with green lenses remains the most traditional choice.

Frequently Asked Questions
Can I put prescription lenses in the Ray-Ban RB4387?
Yes, the RB4387 is fully prescription-ready. The full-rim design and 56mm lens width accommodate single-vision, progressive, bifocal, and polarized prescription lenses. The frames are compatible with most prescriptions due to their moderate 6-base curve.
What face shapes work best with the RB4387?
The RB4387's square shape is ideal for round and oval faces, as the angular lines add definition. The 56mm lens width and 18mm bridge fit medium to large faces comfortably. If you have a very narrow face or high cheekbones, you may want to try them on first to ensure a secure fit.
Do the Ray-Ban 4387 sunglasses offer UV protection?
Yes, all RB4387 lenses provide 100% UVA and UVB protection. The polycarbonate lenses block harmful rays and reduce glare, making them suitable for driving, beach days, and general outdoor use.
How does the RB4387 compare to the Ray-Ban Justin?
The RB4387 is slightly smaller and more refined than the Justin (RB4165). The Justin has a 55mm lens with a rubberized finish and larger coverage, while the RB4387 features a 56mm lens with a sleeker acetate build and keyhole bridge. The 4387 is better for those who want a modern square frame without the Justin's bold, sporty look.
What comes with the Ray-Ban RB4387 sunglasses?
Authentic RB4387 sunglasses come with a Ray-Ban branded case (design may vary), a microfiber cleaning cloth, and product documentation. All models are manufactured by Luxottica and backed by a one-year manufacturer's warranty.
Are the transparent frame options durable?
Yes, the transparent acetate frames are made from the same high-quality nylon and propionate materials as the solid-colored versions. Acetate is lightweight yet durable and maintains its shape over time. Proper care—storing them in the case and cleaning with a microfiber cloth—will keep them looking new.

Ray-Ban RB4387 vs. Justin 4165 vs. New Wayfarer 2132
If you're deciding between the RB4387, the Justin, and the New Wayfarer, you're looking at three distinct takes on Ray-Ban's square frame DNA. Here's how they stack up.
RB4387: The Modern Middle Ground
The RB4387 sits between the Justin and the Wayfarer in both size and style. Its 56mm lens is slightly larger than the Wayfarer but more refined than the Justin. The keyhole bridge and transparent frame options give it a contemporary edge without feeling too trendy. It's the best choice if you want a modern square frame that's versatile enough for both casual and dressier settings.
Justin 4165: Bold & Sporty
The Justin is Ray-Ban's sportiest square frame. At 55mm, the lenses are large and provide excellent coverage. The rubberized finish and 8-base curve give it a wraparound feel that's great for outdoor activities. However, the Justin's bold look and bulkier build make it less suitable for formal occasions. If you want maximum sun protection and a statement frame, the Justin is your pick.
New Wayfarer 2132: The Timeless Classic
The New Wayfarer is the most iconic of the three. Its trapezoidal shape and pantoscopic tilt have been popular since the 1950s, and it suits nearly every face shape. The smaller 52-55mm lens options make it more subtle and versatile. However, if you prefer a more modern look or need larger lenses, the RB4387 or Justin may be better fits.
Our Recommendation
Choose the RB4387 if you want a sleek, modern square frame with a keyhole bridge and transparent options. It's the most versatile of the three and works for both casual and semi-formal settings. Go with the Justin if you need a larger, sportier frame with maximum coverage. Pick the New Wayfarer if you prefer a smaller, classic design with timeless appeal.
