Designed to Dale Earnhardt Jr.'s exact specifications, the Dirty Mo is your first-place trophy no matter how you finish. The Spy Dirty Mo Sunglasses feature custom-built, high-quality propionate frames with custom metal details and 8mm stop hinges. The 8 x 4 base toric ARC polycarbonate lenses provide 100% UVA, UVB, and UVC protection to fully shield your eyes against harmful rays.
/HAPPY LENS: 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.
ARC LENSES: Based on space-age technology, ARC (Accurate Radius Curvature) lenses are injected in a unique, tapered shape to provide optically correct, distortion-free viewing at all angles, ensuring against discomfort and eyestrain.
TRIDENT POLARIZED: 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.
