Sources: costadelmar.com (580 lens page, product pages, warranty page, lens guide) and bajiosunglasses.com (lens technology, lens colors, returns and policies pages, product listings), checked September 16, 2026. Regular prices shown; both brands run sales.
Lens technology: 580 vs LAPIS
Costa 580 is named for the yellow light it filters. Costa says blocking harsh yellow light at 580 nm "boosts the amounts of red, greens and blues naturally, enhancing colors and contrast," and that the lenses cut haze and blur.
Bajío LAPIS leads with blue light. Bajío says its lenses block 95% of blue light up to 445 nm. Bajío's lens spec sheet also lists yellow light blocking at 580 nm for each lens (88% to 95%), so the two approaches overlap more than the marketing suggests.
Both brands sell polarized glass and polycarbonate. The material choice (glass for clarity and scratch resistance, polycarbonate for light weight and impact resistance) matters as much as the brand. We cover that in glass vs polycarbonate fishing sunglasses, and Costa's version of the choice in Costa 580P vs 580G.
Price
- Polycarbonate: basically even on popular fishing frames. Costa 580P is $212 with gray lenses and $233 with mirror lenses on the Fantail, Reefton and Tuna Alley. Bajío is $219 across the board. Costa also has some newer frames with 580P from $136.
- Glass: Bajío is cheaper on comparable fishing frames. $269 on every frame, versus $296 for Costa 580G on core frames and $284 to $309 on Pro Series. Some newer Costa frames list 580G from $225.
- Sales: both brands discount. On September 16, Bajío had some colorways at 30% off ($153.30 poly, $188.30 glass).
Warranty and repairs
This is the biggest difference, and it changed recently. Costa moved from a limited lifetime warranty to a two-year limited warranty in November 2022. It covers manufacturing defects. Scratched lenses and accidental damage aren't covered; they go through Costa's paid Repair and Replacement Program.
Bajío offers a limited lifetime warranty against manufacturing defects. It doesn't cover accident damage like scratches, cracks or hinge damage, but Bajío lists a flat $90 charge for any repair.
Neither warranty covers the stuff that usually happens on a boat: a scratched lens, a pair that got stepped on. Budget for repairs either way.
Freshwater fit
Both brands point freshwater anglers to copper. Costa's lens guide says "for freshwater and inshore, green mirror and copper are great options," with sunrise silver mirror for low light at dawn and dusk. Bajío says copper lenses "are best for inshore and freshwater fishing," and its lens color pages mention walleye, bluegill, smallmouth and trout.
What neither builds a lens or frame around: crappie, panfish or ice fishing, the heart of a lot of Midwest freshwater.
Which should you buy?
- Bass and big-water freshwater: either brand in copper or green mirror. Let price and warranty break the tie.
- Sight fishing, clarity first: glass from either. Bajío's $269 glass costs less than Costa's core 580G.
- Kayak, rough use, lighter pair: polycarbonate from either brand.
- Keeping one pair for years: Bajío, for the lifetime defect warranty and a known $90 repair price.
- Finding an exact frame or lens color: Costa, with far more frames and lens combinations to choose from.
