The Ray-Ban Gina RB4399 sunglasses bring a fresh take on square frames with their distinctive geometric shape. These unisex sunglasses feature thick, curved propionate frames that blend rounded lower edges with squared, angular upper lines—a design that adds visual interest without sacrificing wearability. The bold silhouette and well-defined lens perimeters create a statement look that works equally well with tailored outfits or casual weekend wear.
Design and Construction
Built from lightweight propionate, the Gina offers durability and all-day comfort. The frames feature Ray-Ban's signature metal rivets at the hinges and an embossed logo on the temples, maintaining the brand's heritage while pushing into contemporary territory. Wirecore temples curve gently inward for stability behind the ears, and the high-bridge fit accommodates a wider range of face shapes. Available in 51mm and 53mm lens widths with a 21mm bridge and 140mm temples, the Gina fits medium to larger faces comfortably.
Lens Options and UV Protection
The RB4399 is available with classic green or brown lenses, blue-tinted options, and polarized variants that eliminate glare for outdoor activities. All lenses provide 100% UV protection. The frame is fully prescription-ready, so you can add your Rx through your optician or order custom lenses to match your vision needs—single vision, progressive, or sun lenses with your prescription built in.
Who It's For
The Gina's square-geometric shape flatters oval and round face shapes particularly well, adding definition without overwhelming your features. The medium-sized fit and versatile design make these sunglasses suitable for anyone looking for a modern frame that doesn't follow fleeting trends. Whether you need everyday sun protection or a prescription-ready frame that stands out, the RB4399 delivers Ray-Ban quality at an accessible price point.

Frequently Asked Questions
Are Ray-Ban Gina 4399 sunglasses prescription-ready?
Yes, the Ray-Ban Gina RB4399 is fully prescription-ready. The propionate frame can accommodate single vision, progressive, or prescription sun lenses. You can order custom prescription lenses through your optician or directly from authorized Ray-Ban retailers. The frame's 51mm and 53mm lens widths provide enough surface area for most prescription ranges.
What face shapes work best with the Ray-Ban Gina RB4399?
The Gina's square-geometric shape works best for oval and round face shapes. The angular upper lines and rounded lower edges add definition to softer facial features. The medium-sized frame (51mm or 53mm lens width) and high-bridge fit make it versatile for most face types, though those with very angular or square faces may prefer rounder styles.
What is the difference between the 51mm and 53mm sizes?
The Ray-Ban Gina RB4399 is available in two lens widths: 51mm and 53mm. Both share the same 21mm bridge width and 140mm temple length. The 51mm size suits smaller to medium faces, while the 53mm offers more coverage for medium to larger faces. The overall frame shape and design remain identical across both sizes.
Are polarized lenses available for the Gina 4399?
Yes, several Ray-Ban Gina RB4399 variants come with polarized lenses, including the 901/58 (Black/Green Polarized) and 6429M3 (Grey/Grey Gradient Polarized) options. Polarized lenses remove nearly 100% of surface glare, making them ideal for driving, water activities, and bright outdoor conditions. All lenses provide 100% UV protection.
What material is the Ray-Ban Gina frame made from?
The Ray-Ban Gina RB4399 frame is made from propionate, a lightweight and durable plastic material. Propionate offers excellent comfort for all-day wear, holds its shape well, and is hypoallergenic. The temples also feature wirecore construction for a secure, customizable fit behind the ears.
How does the Ray-Ban Gina 4399 fit compared to other Ray-Ban models?
The Gina RB4399 features a high-bridge fit and medium sizing (51-21-140 or 53-21-140). It has a bolder, thicker frame profile compared to classic models like the Wayfarer or Erika. The wirecore temples curve inward gently for stability, and the irregular geometric lens shape creates a more contemporary look than traditional square or round Ray-Ban styles.

Ray-Ban Gina 4399 vs. Similar Square Frames
If you're drawn to the Ray-Ban Gina RB4399's bold square-geometric design, you might also consider these alternatives from our collection:
Ray-Ban Gina 4399 vs. Ray-Ban Bill 2198
Both the Gina and the Bill represent Ray-Ban's modern approach to square frames. The Gina RB4399 features rounded lower edges that transition to squared upper lines, creating a softer, more versatile geometric shape. The Bill 2198 takes a slightly different approach with its own geometric interpretation. Both are prescription-ready, made from durable propionate, and priced similarly ($148–$218 for the Gina, $125–$244 for the Bill). Choose the Gina if you prefer the irregular geometric lens shape and high-bridge fit; consider the Bill if you want a different take on contemporary square styling.
Ray-Ban Gina 4399 vs. Ray-Ban 4376
The Ray-Ban 4376 offers a more traditional square shape at a lower entry price ($111–$178). While both are unisex frames suitable for everyday wear, the Gina stands out with its bolder profile, thicker frame perimeters, and distinctive geometric lens shape. The 4376 is a solid choice if you want a cleaner, less statement-making square frame. The Gina is the better pick if you're looking for a frame that blends classic square styling with modern, eye-catching design details—and don't mind the slightly higher price for that distinctive look.
All three models are prescription-ready and offer Ray-Ban's signature quality and UV protection. Your choice comes down to how bold you want your frames to be and which geometric interpretation speaks to your personal style.
