The Smith Turnkey Sunglasses have a fantastic rimless frame design for unobstructed views. The Turnkey sunglasses were built with ChromaPop polarized lenses for optimum color and increased clarity to allow you to see more vibrant and truer colors. These Smith Shades also feature TLT Polarized Glass lenses to protect your eyes from harmful UVA/B/C rays while keeping your vision distortion free and reducing glare so you can see more clearly. Made from Evolve frame material, the frames of these Smith Sunglasses are lightweight, durable, and ecologically friendly in their construction. The 8 base curve of the Turnkey provides just enough wrap to protect you from the elements while still looking good. Hydrophobic lens coatings on these Smith sunglasses will prevent water from streaking the lens and the hydrophilic Megol Nose and temple pads give the Turnkey a great fit and will provide a firm grip even during hot and humid days. The Smith Turnkey Sunglasses offer increased clarity and unobstructed views along with a flexible and comfortable fit.
