Frequently Asked Questions
Are the Ralph 5138 sunglasses prescription-ready?
Yes, the Ralph RA5138 frames are fully prescription-ready and compatible with single-vision, progressive, and polarized prescription lenses. The durable acetate construction and secure fit make them an excellent choice for custom Rx lenses. Many optical retailers offer prescription lens installation for this model.
What face shapes work best with Ralph 5138 square sunglasses?
The Ralph 5138 square frames are designed to flatter all face shapes, though they're particularly complementary for round and oval faces by adding structure and definition. The 58mm lens width provides generous coverage without overwhelming smaller features, and the subtle upswept browline softens the square shape for universal wearability.
Do Ralph 5138 sunglasses come with UV protection?
Yes, all Ralph RA5138 sunglasses include 100% UV protection to block harmful UVA and UVB rays. The gradient lenses transition from dark to light tint while maintaining full UV coverage across the entire lens surface, and polarized versions add glare reduction for enhanced visual comfort.
What size are the Ralph 5138 sunglasses?
The Ralph RA5138 measures 58mm lens width, 16mm bridge width, and 135mm temple length (58-16-135). This is considered a medium to large fit that provides generous eye coverage. Customers consistently report the sizing runs true and fits comfortably without feeling tight or loose.
What material are Ralph 5138 frames made from?
The Ralph RA5138 frames are constructed from acetate, a durable, lightweight, and flexible plastic material that's hypoallergenic and comfortable for all-day wear. The temples feature metallic accents with double-screw detailing and the RALPH logo, combining plastic durability with refined metal finishing touches.
Are polarized lenses available for the Ralph 5138?
Yes, the Ralph RA5138 is available with polarized gradient lenses in select colorways, including the Black/Polar Gray Gradient and Shiny Black on Nude/Polar Gradient Brown options. Polarized lenses reduce glare from reflective surfaces like water, snow, and pavement while maintaining the gradient tint aesthetic.

Ralph 5138 vs. Ralph 5203: Square or Cat-Eye?
If you're choosing between Ralph by Ralph Lauren frames, the RA5138 and RA5203 represent two distinct style directions at nearly identical price points. Both are acetate women's sunglasses with gradient lens options, prescription compatibility, and 100% UV protection—but the shape makes all the difference.
The Ralph 5138 offers a square silhouette with full acetate temples, metallic accents, and a 58mm lens that provides generous eye coverage. It's the more universally flattering option, working across round, oval, and square face shapes. Customers praise the secure fit and substantial feel of the all-acetate construction.
The Ralph 5203 brings vintage-inspired cat-eye styling with sleek metal temples and a smaller 54mm lens. It's ideal if you want a more feminine, retro look and have a square or oval face that benefits from the upswept cat-eye angles. The metal temples create a lighter, more delicate aesthetic compared to the 5138's bolder acetate arms.
Choose the 5138 if: You want maximum coverage, a universally flattering square shape, and a more substantial frame feel. It's the safer choice for first-time Ralph buyers or anyone seeking an everyday pair that works with most outfits and face shapes.
Choose the 5203 if: You prefer vintage cat-eye styling, have a square or oval face, and want a lighter frame with metal temple details. The smaller lens size suits petite to medium faces, and the cat-eye shape makes more of a fashion statement.
