The Spy Optic Logan 670939 sunglasses deliver serious performance in a bold wrap-around design. Built from lightweight yet virtually indestructible Grilamid—a high-strength polymer known for flexibility and impact resistance—these frames handle everything from job sites to mountain trails. The full-rim rectangular wrap design provides excellent peripheral coverage, blocking wind and glare from every angle.
What sets the Logan apart is Spy’s Happy Lens technology. Unlike conventional sunglasses that block all blue light, Happy Lenses allow beneficial long-wave blue light to reach your eyes while filtering out harmful UV and short-wave blue light. This selective filtering mechanism targets specific wavelengths, allowing certain blue light through while blocking others. The lenses also enhance color and contrast, so you see richer, more accurate tones without distortion. Available in both polarized and non-polarized options across multiple tints and mirror finishes, including Happy Gray Green, Happy Bronze Polar, and Happy Boost variants.
The 8-base polycarbonate ARC (Accurate Radius Curvature) lenses follow the natural curve of your eye, reducing eyestrain and delivering crystal-clear, distortion-free vision. All lenses provide 100% UV protection. High-quality pin hinges ensure smooth operation and long-term durability. Select variants carry ANSI Z87.1 certification for high-impact resistance, making them suitable for industrial work, shooting sports, and other safety-critical activities.
The Logan measures 61-14-127 (lens width-bridge-temple length in millimeters), fitting most small-to-medium faces. The iconic Spy cross logo appears subtly on each temple. Prescription lenses are available through authorized retailers.
