Providing an expansive field of vision, the Demos Sunglasses feature a large Zeiss single-lens which promotes optimum clarity. With Zeiss® Anti-Reflective Technology, the lens eliminates reflections from the front and back surfaces of the lens - meaning your eyes receive the greatest light levels possible, improving contrast and definition, reducing eye strain, and ensuring an incredible visual experience. The revolutionary single-lens frame boosts your peripheral vision while integrated ventilation ports prevent fogging. Meanwhile, anti-slip MEGOL elastomer temple inserts, and soft-rubber adjustable nose pad stabilise the fit and ensure long-lasting comfort.
