Costa Del Mar Rincon Sunglasses
Built for Hard-Charging Surfers
Named for the legendary California point break, the Costa Del Mar Rincon carries that same attitude into its design. A classic West Coast straight bridge, sweeping wrap-style lines, and edgy curved temples give this frame a bold silhouette that reads as unmistakably surf-influenced. The oversized shape fits a wide range of faces and serves as a true extra-large option for those who have always struggled to find a frame that actually fills out.
Bio-Based Resin Frame
The Rincon frame is molded from Costa's castor plant bio-based resin, a renewable-source material that delivers the rigidity and impact resistance of conventional plastics without the petroleum dependency. The result is a frame that stays light on the face across a full day on the water, in the lineup, or on the road. Spring hinges at both temples add flex and retention so the frame conforms to your head rather than clamping it, and they absorb the daily stress of putting on and taking off without fatiguing over time.
580 Polarized Lens Technology: 580G vs 580P
Every Rincon ships with Costa's 580 polarized lenses, which filter the 580nm wavelength of light that causes eye fatigue in bright, reflective environments. The Rincon is offered in two lens materials, each with real performance trade-offs worth understanding before you choose.
| Feature | 580G (Glass) | 580P (Plastic Bio-Resin) |
|---|---|---|
| Lens material | Polarized glass | Polarized plastic (bio-based resin) |
| Optical clarity | Highest; glass is the optical benchmark | Excellent; lighter than glass |
| Weight | Heavier | Lighter |
| Scratch resistance | Superior | Good with care |
| Impact resistance | Lower (glass can shatter) | Higher (flexes on impact) |
| Best for | Long days on the water, fishing, driving | Active water sports, travel, everyday use |
| Price range | Higher | Lower |
Both variants use a Base 6 decentered lens curve, which keeps the lens in the optimal position across a wider field of view than a standard flat lens and virtually eliminates the peripheral distortion that causes headaches on long wears.
Lens Curve and Fit
The Rincon's Base 6 decentered curve is not purely aesthetic. Decentered optics shift the optical center of the lens to account for the angle at which light enters a wrap-style frame, correcting the distortion that flat lenses introduce when placed at a curve. The practical benefit is sharp, undistorted vision to the edges of the frame, even at the wide wrap angle the Rincon carries. The frame fit is classified as Regular, and the large lens format suits wearers who want maximum coverage without stepping into a specialty performance silhouette. The nose bridge is fixed with no nosepad adjustment.
Polarization and UV Protection
All 580 lenses are 100% polarized and block 100% of UVA and UVB light. Polarization eliminates surface glare from water, roads, and sand, which is the primary cause of squinting and eye fatigue in coastal environments. The 580 filter adds a second layer by cutting the specific wavelength band that causes the most visual noise in high-reflectance settings, producing a color-enhanced view that makes it easier to see into water and read contrast in changing light.

Frequently Asked Questions
- What is the difference between Costa Rincon 580G and 580P lenses?
- 580G lenses are made from polarized glass, which delivers the highest optical clarity and superior scratch resistance, but adds weight. 580P lenses are made from polarized bio-based plastic, which is lighter and more impact-resistant, making them better suited for active water sports. Both use the same 580 filter technology and Base 6 decentered optics.
- Are Costa Del Mar Rincon sunglasses polarized?
- Yes. All Costa Rincon lenses are 100% polarized and block 100% of UVA and UVB light. The 580 polarized filter eliminates glare from water, sand, and reflective surfaces.
- What frame material is the Costa Rincon made from?
- The Rincon frame is molded from Costa's castor plant bio-based resin, a renewable-source material that provides the durability of conventional plastics at a lighter weight.
- Is the Costa Rincon a good fit for large or wide heads?
- Yes. Costa describes the Rincon as an oversized style for most wearers and an ideal extra-large fit for those with larger heads. The spring hinge system adds flex to accommodate a wider range of head widths comfortably.
- What does the Base 6 Decentered lens curve mean on the Costa Rincon?
- Base 6 refers to the curvature of the lens. Decentered means the optical center is shifted to correct for distortion that occurs when a curved lens wraps around the face. The result is sharp, undistorted vision across the full width of the lens, including the peripheral edges.
- Where can I buy Costa Del Mar Rincon sunglasses?
- The Costa Rincon is available in store and online at Island Water Sports. Visit us in South Florida or call 954-427-4929 for assistance.
- Can the nose bridge on the Costa Rincon be adjusted?
- No. The Rincon has a fixed nose bridge with no nosepad adjustment. The frame is designed with a regular fit profile and the bridge geometry is set at manufacture.
