These are the glasses that enable a golfer to quickly assess a green before making a putt. Their polycarbonate lenses optimize the green portion of the color spectrum, revealing a green's nuances. Ideal for determining one's intended line and pace before a par-saving putt, the lenses reveal higher areas that appear a lighter, yellow-green, while lower areas appear a darker, blue-green. Made from premium-grade resin and coated on both sides to resist scratches, the polycarbonate lenses resist impact 20X better than glass while weighing 3X less. The half-rim nylon frames are lightweight, providing a wide field of view; hydrophilic nose pads and temple tips absorb moisture, keeping the glasses in place. The frames' pin-less hinges seamlessly connect the temples to the frame fronts for durability and a sleek look and feel.
