Costa Del Mar Sunglasses Archives

Costa Del Mar prescription sunglasses combine the brand’s marine-grade frame engineering with custom-surfaced Rx lenses. This gives you the field-tested performance that Costa is known for, calibrated to your individual visual prescription.

Every Costa frame in the collection is prescription-ready and pairs with single vision, bifocal, or progressive lens designs. You can choose from a variety of custom lenses in a range of materials, including impact-resistant polycarbonate, scratch-resistant glass, and high-index plastics.

All Costa sunglasses are 100% polarized. That means a fully polarized film is integrated into the lens during manufacturing to filter horizontally reflected light. This protects you against the kind of glare that bounces off water, paint, snow, sand, and dashboards. The result is reduced eye strain, sharper definitions, and a more accurate read of color and contrast in high-light environments. Costa’s proprietary 580 lens technology takes this further by filtering yellow light at 580 nanometers, which sharpens reds, blues, and greens for noticeably better color separation in outdoor settings.

At RX-Safety, we surface and fit every prescription in our U.S.-based optical lab. You can choose between authentic Costa-branded Rx lenses (preserving the full 580G or 580P optical package, including C-Wall scratch coating and encapsulated mirror finishes) or our in-house digital Rx lenses. These open up a wider range of price points, lens designs, and tint options while maintaining the polarization and high optical clarity you expect from Costa.

The Best of Both Worlds

There’s no need to choose between corrective vision and category-leading polarized performance. The Costa frames you’d buy off the shelf are the same frames we customize. These include Pro models, Untangled Collection frames, lifestyle frames, and full-coverage angling frames.

Clarity on the Water

Anywhere you’re on or near the water, polarization lets you see through surface glare rather than around it. With Costa’s 580 spectral filtering, prescription wearers get the same fish-spotting and structure-reading advantage that makes Costa a fixture among professional anglers and saltwater guides.

Tailored Vision

RX-Safety designs custom Costa prescription sunglasses. We take their leading frames and install your ideal lenses. We cover the full range of lens types, including single vision, lined bifocal (FT-28), digital single vision, and no-line progressive.

Secure & Reliable

Costa frames are at their best when used actively. They include hydrolite rubber on the nose pads and temple tips, which stick to your face more as you sweat more. This keeps the frames firmly in place during activities like hiking, biking, and sports. Pro models take it a step further with ventilation ports near the end pieces and temple channels. These reduce fogging and heat buildup.

Risk-Free Customization

RX-Safety offers free shipping and free returns across the full Costa prescription sunglasses category. Our optical team is available six days a week if you’d like personalized guidance while customizing your next pair. Just reach out, and we’ll tell you how we can help and how we protect your purchase with our lens warranty.

Frequently Asked Questions

Yes. 100% of Costa sunglasses feature integrated polarized technology. Costa does not produce a non-polarized lens line. Polarization is a defining brand characteristic, and the polarized film is laminated within the lens rather than applied as a surface coating. This means its polarization can’t wear off or peel like other lenses. That matters in environments with high light reflection, like the ocean, large lakes, snow, or open highway driving.

Yes. RX-Safety specializes in fitting Costa frames with custom Rx lenses. Our offerings include single vision, FT-28 bifocal, digital single vision, and no-line progressives. You can choose whatever works best for you, without sacrificing polarization, UV blockage, or 580 color enhancement. Our in-house Rx lenses also include polarization across all tint options.

580G is Costa’s LightWave glass lens. It’s 22% lighter and 20% thinner than standard polarized glass lenses, and it offers Costa’s highest level of scratch resistance and optical clarity. 580P is the polycarbonate version. It’s lighter than glass overall, more impact-resistant, and a better fit for high-activity sports where lens breakage is a concern. Both types include 100% polarization, 100% UV blockage, and 580 spectral filtering. The key trade-off is clarity and scratch resistance (580G) versus weight and impact resistance (580P).

Yes. We offer both authentic Costa-branded Rx lenses and our own RX-Safety digital Rx lenses. The Costa-branded option preserves the original lens technology and tint catalog. Our in-house digital lenses give you wider customization on lens designs, tints, coatings, and price.

Blue Mirror is the best Costa lens color for offshore fishing. It has a gray base with 10% light transmission, which has been tuned for the highest-glare environments. That being said, Green Mirror is a better choice for inshore flats and freshwater fishing. Its copper base delivers a stronger contrast in variable lighting, so you can see the bottom more clearly.

Many are. Costa’s bio-resin frames are part of the Kick Plastic initiative and are produced from castor-bean-derived plastic resin rather than petroleum-based plastic in an effort to reduce reliance on fossil fuels. Bio-resin is used across most of Costa’s nylon frame line. The Untangled Collection is built from recycled fishing net material that’s recovered before becoming waste. The frames are made in partnership with Bureo and currently incorporate 97% recycled fishing net material.

Hydrolite is Costa’s proprietary, hypoallergenic rubber, used on nose pads and temple tips. It’s engineered to grip more firmly when wet. The more you sweat, the more it locks into place. This is why Costa frames stay seated during running, biking, casting, and other activities that would slip a standard acetate frame off your face.

Yes. Prescription sunglasses qualify as a medical device under most HSA and FSA plans, and you can use those cards directly at checkout on RX-Safety. If your plan requires itemized documentation, our system can generate a receipt that breaks out the prescription lens portion of the order.

Yes. Costa Del Mar offers a limited warranty covering defects in the materials and craftwork of the frame and lens. RX-Safety extends this warranty to the prescription lens surfacing we perform in our own lab. If you experience an issue with the Rx component, you’d reach out to us. If you experience frame defects, then that claim runs through Costa directly.

Costa categorizes frames as Small, Medium, Large, and Extra Large based on overall coverage. Each product page includes specific measurements like lens width, bridge distance, temple length, and total frame width. If you have a current pair of glasses or sunglasses that fit well, those measurements (usually printed on the inside of the temple) are the most reliable reference for matching size. Our customer service team can also help you compare frames to a model you already own.

RX-Safety surfaces every Costa prescription order in our U.S.-based optical lab. You can select from the following lens designs:

Single Vision: One corrective zone for distance, intermediate, or near. The most common Rx for sunglasses.
Digital Single Vision: These offer wider clear zones at the periphery and reduced edge distortion. They’re often used for stronger prescriptions and use cases like fishing and driving, where peripheral clarity matters.
FT-28 Bifocal: A traditional lined bifocal with a 28mm reading segment. Best for users who want a sharply defined near-vision zone.
No-Line Progressive: A graduated lens with distance, intermediate, and reading zones. These are blended without any visible line and are a good fit for everyday wear.

Lens material options include:

Polycarbonate: Impact-resistant and lightweight. The most common safety and sports material.
CR-39: A traditional plastic lens with strong optical quality, used where impact resistance is less critical.
Glass: Highest scratch resistance and optical clarity. However, these are heavier than poly or CR-39, so they’re not right for impact-prone environments.
High-Index (1.67, 1.74): Thinner, lighter lenses for stronger prescriptions, reducing the “coke bottle” effect at the edges.

All Rx lens options can be paired with polarization, mirror coatings, anti-reflective backside treatment, and scratch-resistant hard coats.
