The Costa Del Mar Tybee sunglasses bring the relaxed spirit of Georgia’s Tybee Island to a rectangular acetate frame built for water, sun, and everyday wear. Named after the laid-back beaches near Savannah, the Tybee is part of Costa’s Del Mar Collection—a line of prescription-ready lifestyle frames for people who love the ocean even when they’re not on it.
Costa didn’t just polarize these lenses—they re-engineered how sunglasses handle light. The 580G glass lenses filter out harsh yellow light and harmful high-energy blue (HEV) light in the 400–500nm range, cutting the haze and eye fatigue that comes from short-wavelength blue. What’s left? Reds, greens, and blues that pop with definition you won’t find in standard polarized glass. Anglers rely on 580 lenses to spot fish in the water; everyone else just enjoys how much sharper the world looks.
The glass is Costa’s LightWAVE construction—20% thinner and 22% lighter than typical polarized glass, with mirrors encapsulated between layers so they never scratch off. The C-Wall coating adds scratch resistance and repels water, oil, and sweat. You get 100% UV protection, 99.9% polarization efficiency, and optical clarity that rivals anything on the market. 580P polycarbonate lenses are available in select frame colors including tortoise and black kelp finishes, offering lighter weight and more impact resistance, though many Costa enthusiasts prefer the glass versions for superior optical clarity.
The Tybee’s full-rim rectangular shape suits average to wider faces (55mm lens width, 19mm bridge, 140mm temples). The acetate is durable and holds its shape through daily use, with adjustable core wire in the temples for a custom fit. Select colors use Costa’s Ocean Current bio-acetate, made from 67% natural and renewable materials. The frame is prescription-ready—you can add your Rx in either 580G glass (up to moderate prescriptions) or 580P polycarbonate (higher powers).
Available in 13 variants spanning tortoise, black kelp, shiny light gray crystal, and ocean current blue frames, paired with lenses from copper and green mirror to gray gradient and blue mirror. Each lens tint is tuned for specific conditions: green mirror excels on the flats and inshore, blue mirror cuts glare offshore, gray is the all-purpose choice.
The Tybee fits men with average-sized heads looking for a medium-coverage frame (6-base curve) that balances style and performance. It’s at home on a boat, at the beach, or running errands—casual enough for everyday wear, technical enough for serious time on the water. If you need prescription polarized sunglasses with real optical performance, the Tybee is one of the few frames that delivers Costa’s full 580 technology in Rx form.
