DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Ray-Ban RB3750 sunglasses bring a modern square silhouette to the brand's legendary metal frame heritage. Built with a full-rim stainless steel front and durable propionate temples, these unisex frames deliver the kind of construction quality Ray-Ban has been known for since 1937.

The square lens shape offers generous coverage without feeling oversized, while the metal bridge and adjustable nose pads let you dial in a secure, personalized fit. Available in two sizes—59mm and 62mm—the RB3750 accommodates a range of face shapes and sizes. The gunmetal, black, and copper frame options pair with classic Ray-Ban lens tints: G-15 green for natural color perception, dark grey for glare reduction, and blue for a contemporary look.

Prescription-Ready Metal Construction

These frames are fully prescription-ready, so you can add your Rx lenses and wear them as everyday eyewear or prescription sunglasses. The metal construction keeps the weight down while the propionate temple tips add comfort for all-day wear. The adjustable nose pads—a feature metal frames are known for—ensure the frames sit exactly where you need them, which is especially important when you're adding prescription lenses.

Ray-Ban's crystal lens material provides optical clarity and scratch resistance. All lenses block 100% of UVA and UVB rays, protecting your eyes whether you're driving, at the beach, or just running errands. The full-rim design secures the lenses firmly in place, adding to the frame's durability.

Who They're For

The RB3750 works well if you want a square frame with a bit more structure than acetate styles but less bulk than wraparound sport designs. The 59mm size fits most average faces, while the 62mm is better for larger builds. The metal-and-propionate mix gives you styling flexibility—professional enough for work, casual enough for weekends. If you've been wearing Wayfarers or Justins and want to try a metal frame with similar coverage, this is a solid option.

Frequently Asked Questions

Are Ray-Ban 3750 sunglasses prescription-ready?

Yes, the Ray-Ban RB3750 frames are fully prescription-ready. You can add single vision, bifocal, or progressive lenses through most optical retailers. The metal frame construction and adjustable nose pads make them ideal for prescription use, as they allow for precise optical alignment and a customized fit.

What size should I choose: 59mm or 62mm?

The 59mm lens width is considered a standard fit for most average-sized faces, while the 62mm is a larger fit designed for bigger faces or those who prefer more coverage. Both sizes have an 18mm bridge width and 145mm temple length. If you typically wear medium-sized sunglasses, start with the 59mm.

What is the frame made of?

The RB3750 features a full-rim metal front (stainless steel) with propionate temple arms. This combination gives you the durability and adjustability of metal frames with the comfort and flexibility of propionate on the parts that touch your head. The frame also includes adjustable metal nose pads for a customized fit.

Do these sunglasses have UV protection?

Yes, all Ray-Ban RB3750 lenses provide 100% UVA and UVB protection. The lenses are made from crystal (glass) material, which offers excellent optical clarity and scratch resistance while blocking harmful ultraviolet rays. This protection is built into the lens material, not just a coating.

What's the difference between metal and acetate Ray-Ban frames?

Metal frames like the RB3750 are typically lighter, more durable, and feature adjustable nose pads for a customized fit. Acetate frames offer more color variety and a bolder look but don't have adjustable nose pads. Metal frames are often preferred for prescription use because the adjustable nose pads allow for better optical alignment.

How do I clean and maintain metal Ray-Ban sunglasses?

Clean the lenses with a microfiber cloth and lens cleaner or mild soap and water. For the metal frame and nose pads, use a soft damp cloth to remove oils and debris. Avoid harsh chemicals that can damage the metal finish. Store them in the protective case when not in use to prevent scratches and maintain the frame's shape.

Ray-Ban RB3750 vs. Similar Square Metal Frames

If you're considering the Ray-Ban RB3750, you're likely drawn to modern square metal frames that balance style with prescription-ready functionality. Here's how the RB3750 stacks up against other popular options in our collection.

RB3750 vs. Ray-Ban Square 1971

The Square 1971 is Ray-Ban's vintage-revival icon from the '70s, featuring a thinner, more delicate metal construction compared to the RB3750's fuller square profile. If you want a retro-inspired look with lighter weight, the 1971 delivers that classic gold or silver aesthetic. However, the RB3750 offers more coverage and a sturdier feel, plus the propionate temple tips add comfort for all-day wear. The 1971 starts slightly lower in price but has fewer color options. Choose the 1971 for vintage style, the RB3750 for modern versatility and coverage.

RB3750 vs. Ray-Ban 3588

The RB3588 is another contemporary square metal frame in Ray-Ban's numbered series, offering similar construction and styling to the RB3750. Both feature full-rim metal fronts, adjustable nose pads, and prescription-ready designs at comparable price points. The main differences come down to subtle design details and temple construction—the RB3750's propionate temples may offer slightly more comfort, while the 3588 maintains an all-metal aesthetic. If you're choosing between these two, try both on if possible, as the fit and feel will be your best guide.

RB3750 vs. Ray-Ban Clubmaster Metal 3716

The Clubmaster Metal 3716 takes a completely different design approach with its iconic browline style, combining metal rims with an acetate brow bar. While both frames are metal, prescription-ready, and feature adjustable nose pads, the Clubmaster has a more distinctive retro-formal look compared to the RB3750's clean square aesthetic. The Clubmaster Metal also sits at a higher price point ($144-276). Choose the Clubmaster Metal if you want that classic browline statement; go with the RB3750 if you prefer a more understated, versatile square frame that works in more settings.

Bottom line: The RB3750 hits a sweet spot for customers who want a modern square metal frame with solid construction, prescription compatibility, and everyday versatility. It's less retro than the 1971, more distinctive than the 3588, and more casual than the Clubmaster Metal—making it an excellent choice for your primary pair of sunglasses.
