northwave devil black/white - smoke + clear lenses

Northwave's Devil frame is sleek and minimalist, with no side bars for unobstructed peripheral sight. The nose pads can be adjusted by hand for a close and comfortable fit. The frame comes with two interchangeable lenses to suit different light conditions. The smoke lens is best suited to good light conditions (a moderately sunny day or a winter's day), it transmits 22% of light and does not alter colour perception. The clear lens offers optimum visibility in poor light conditions, perfect for use during the night to protect the eyes from any foreign particles, it transmits 92% of light. Lightweight and impact/abrasion resistant, Northwave's polycarbonate lenses possess first rate optical features, such as their low refraction index and complete filtering of U.V rays. The lenses curve fully around the orbital bone to fully protect eyes from sun rays and foreign particles. To avoid any distortion of the field of vision, Northwave re-align the focal centre of the lenses so that it is aligned with your eyes, maintaining the line of vision. All of Northwave's lenses are undergo a treatment to make their surface very smooth, meaning drops of water slide off the lenses, maintaining vision in difficult weather conditions.
