Built for Adventures on and Near the Water
The Costa Del Mar Tasman Sea is a wrap-style performance sunglass engineered to keep up with serious outdoor pursuits. Costa Del Mar has spent decades perfecting optics for anglers, surfers, and anyone who spends time on the water, and the Tasman Sea carries that heritage in a frame that looks as good off the water as it performs on it.
580P Polarized Lens Technology
The Tasman Sea is fitted with Costa's 580P lens system. The 580 designation refers to Costa's proprietary lens technology, which is designed to block yellow light at 580 nanometers (the wavelength responsible for haze and glare) while transmitting the wavelengths that sharpen contrast and color definition. The result is a noticeably cleaner, more detailed view of your surroundings, particularly on bright reflective surfaces like open water, wet sand, and asphalt.
The P in 580P stands for polycarbonate. This lens material offers meaningful impact resistance and keeps the frame lightweight for all-day comfort, making it a practical choice for active use. Full polarization cuts horizontal glare from water and hard surfaces, reducing eye fatigue on long days outside.
Frame Construction
The Tasman Sea uses a full wrap frame profile that delivers peripheral coverage and a secure fit during active movement. The frame is designed to stay put whether you are paddling, running a boat, or moving between environments. Costa builds its frames to withstand the corrosive effects of saltwater, sunscreen, and sweat -- conditions that degrade ordinary eyewear quickly.
Why Costa Del Mar
Costa Del Mar is an American manufacturer of polarized sunglasses with roots in the fishing and outdoor communities. Their lenses are designed specifically around the visual demands of water-based activities, where glare management and color contrast are not optional extras but functional requirements. The Tasman Sea is a direct expression of that focus: purpose-built optics in a frame durable enough to take real use.
