Own the waves in style and comfort with the Spy McCoy Sunglasses. Custom-built, high-quality, Matte Black propionate frames provide strength and durability, while the custom metal details add a touch of unique design. Based on space-age technology, the 8-base Blue Spectra tinted ARC (Accurate Radius Curvature) polycarbonate lenses provide 100% UVA, UVB, and UVC protection to fully shield your eyes against harmful rays. Blue Spectra tinting offers superior contrast and color in full sunlight. This is perfect for open water fishing and other water activities. Spy Happy Lens technology lets in the good long-wave blue light that promotes balance in the body's circadian rhythm, blocks the harmful bad rays, and combines crisp, color contrast-enhancing lenses and Trident Polarization for the ultimate viewing experience. Trident Polarized lenses block sunlight's glare-filled rays and filter the chaos into a stream of clean, clear light. Trident Polarized is layered and sealed within Spy's injected ARC lenses so your polarization will stay with you for the life of your glasses - no scratching, delaminating, or hazing of your polarized filter.
