The Costa Del Mar Rincon 9018 Sunglasses bring West Coast surf culture and serious optical performance together in one of Costa’s most popular frames. Named after the legendary California point break, the Rincon features a bold rectangular shape with a classic straight bridge, wraparound coverage, and edgy curved temples that deliver both style and function for fishing, beach days, and everyday wear.
What sets the Rincon apart is Costa’s proprietary 580 lens technology—a multi-patented system that filters out harsh yellow light at 580 nanometers on the visible spectrum. By blocking this specific wavelength, the lenses naturally boost reds, greens, and blues, delivering enhanced color, sharper contrast, and superior definition. All 580 lenses provide 100% UV protection and also absorb high-energy visible (HEV) light known to cause eye damage.
The Rincon is available with two lens materials: 580G glass lenses offer the most optically correct clarity and are scratch-proof, while being 20% thinner and 22% lighter than average polarized glass. 580P polycarbonate lenses are the most impact-resistant option, ideal for active use, and include a scratch-resistant coating. Both are fully polarized to cut glare on water, snow, and pavement.
The frame is constructed from lightweight, durable bio-based TR90 nylon derived from castor plants—corrosion-resistant and able to maintain its shape in harsh ocean elements and extreme heat. Integral spring hinges provide a flexible, secure fit, while Hydrolite rubber nose pads and temple tips get tackier as you sweat, keeping the sunglasses locked in place during activity.
The Rincon offers an extra-large fit (frame width 133mm, lens width 63.5mm, bridge 12.5mm, temple 135mm), making it a go-to choice for those with broader faces or anyone who prefers generous coverage. The 6-base curve also makes the Rincon highly prescription-friendly, so you can add your Rx and enjoy Costa’s legendary optics with vision correction.
Anglers, boaters, and outdoor enthusiasts love the Rincon for its unmatched visual clarity and all-day comfort. The large lenses provide excellent protection from UV rays and side glare, while the versatile design transitions easily from the water to casual weekend wear. If you need a do-it-all frame that keeps up with fishing trips, lunch runs, and afternoon hangouts, the Rincon delivers.
