Ray-Ban 4387F vs Similar Square Frames
If you're considering the Ray-Ban RB4387F, you're likely drawn to modern square acetate frames. Here's how it stacks up against other popular options in our collection.
RB4387F vs Justin 4165
The Ray-Ban Justin 4165 is the more casual, oversized cousin. It features a rubberized frame finish and slightly larger lenses (54mm vs 56mm), giving it a bolder street-style look. The Justin works well if you want maximum coverage and don't need the low bridge fit. However, if you have higher cheekbones or a flatter nose bridge, the 4387F's engineered fit will be far more comfortable for all-day wear. The Justin also tends to feel heavier and bulkier on smaller faces.
RB4387F vs 4306
The Ray-Ban 4306 offers a similar square acetate design in a comparable size and price range. The key difference? The 4306 only comes in standard fit. If regular frames slide down your nose or rest on your cheeks, the 4387F's low bridge design solves that problem. Both are prescription-ready and offer multiple color options, but the 4387F has more photochromic Evolve lens choices for adaptive light protection.
RB4387F vs Erika 4171
The Ray-Ban Erika 4171 takes a different approach with its soft, rounded shape and keyhole bridge. It's an excellent choice if you have a square face with a strong jawline, as the curves balance angular features. But if you have a round or oval face, the 4387F's square lines will provide better definition. The Erika also lacks a low bridge fit option, making the 4387F the smarter pick for anyone who needs that specialized fit.
Bottom line: Choose the RB4387F if you need low bridge fit, prefer structured square styling, or have a round/oval face that benefits from angular frames. It's the most versatile option for diverse face shapes and bridge heights.
