Costa Del Mar Replacement Lenses
318 frame models · Crafted in Italy · 60-day perfect-fit guarantee
Costa was founded in 1983 in Daytona Beach, Florida, by fishermen who wanted purpose-built sunglasses for offshore conditions. The brand pioneered 580 lens technology — selectively absorbing the yellow light at 580 nanometers to enhance reds, greens, and blues underwater, making fish and reef structure easier to spot. Now owned by EssilorLuxottica, Costa remains the dominant choice for saltwater anglers, sport fishermen, and coastal outdoor users.Replacement lenses through Costa’s official program are limited in color and expensive. Our aftermarket lenses for Costa Blackfin, Fantail, Tuna Alley, Reefton, Fisch, and other frames deliver equivalent polarization with the same fishing-specific tints — Blue Mirror, Green Mirror, Copper, Sunrise Silver Mirror — at lower cost.

Which color, for what light?
Every Costa Del Mar frame is available in our full range of polycarbonate replacement lenses. Find the right tint for how you actually use them.
Filter categories follow EN ISO 12312-1, based on visible light transmission. Most tints are Category 3. Clear and Blast Yellow are Category 0, for indoor and low-light use. Photochromic shifts with UV exposure, from Category 1 in its clear state to Category 2 when fully dark. We sell no Category 4 lens; note that Category 3 tints are not suitable for driving at night. Shatter-resistant polycarbonate, anti-reflective and oleophobic coatings included. Full technical specs on each product page.
Why The Lens King for your Costa Del Mar
Costa Del Mar serves the saltwater angler — Tampa Bay tarpon, Florida Keys bonefish, Cabo billfish. The lens job is to cut surface glare on water and reveal what swims below. Our Costa-compatible lenses target exactly that.
Polarized polycarbonate, copper or amber base for low-light water visibility, green or blue mirror finishes available. 580-equivalent specifications: yellow light absorption, blue HEV cut, chromatic edge enhancement on water surfaces. Compatible with Fantail, Brine, Tuna Alley, Saltbreak, and 30+ other Costa frames.
For inshore, offshore, or sight-fishing flats — our lens choice matters more than the frame, and we make the lens job our priority.

Not sure where to start?
How do I pick the right lens color for my use?
Match the lens to the activity, not the look. Bright sun, beach, snow: dark tints VLT 10–14% (Gray Green, Volcanic Black, mirrored lenses). Variable conditions, driving: brown or photochromic. Overcast, low light, dawn/dusk: yellow or clear VLT 60%+. All-day everyday: Gray Green polarized is the safest bet — neutral colors, glare cut, works in 90% of situations.
Polarized vs Non-Polarized — which one for me?
Get polarized if you drive a lot, spend time near water (beach, fishing, boating), or struggle with road glare. Polarized lenses cut reflected glare from horizontal surfaces. Skip polarized if you fly small aircraft (cockpit screens go black), ski (icy patches become invisible), or use digital screens outdoors (LCD displays become unreadable). For walking around, casual wear, sport: either works.
How do I find my Costa Del Mar model code?
The model code is printed inside the temple arm — usually the left arm, near the hinge or further down towards the ear. Hold the frame open, look at the inner surface of the arm against a light source. You'll see a code like OO9102-01 or RB3025 002/58. The letters/numbers before the dash are the model; what comes after is color and size variants. We match the model code — the variants don't affect lens fit.
Will TLK lenses fit my original Costa Del Mar frame?
Yes, with our 60-day perfect-fit guarantee. Each lens is precision-cut on MEI optical machinery to match the original frame shape, base curve, lens material thickness, and edge profile. We test fit before shipping. If your specific unit was made in an unusual year or modified, send us a photo — we'll confirm compatibility before you order. No-fit happens in less than 1% of orders, and we refund or remake those at no cost.
