These glasses were designed especially with golf in mind. The frame without lenses weighs only nine grams. The temples are just 4.5 mm wide and are cut by laser from titanium which has a thickness of only 0.7 mm. The temple ends are formed in such a way that they remain in place, even when taking a swing. Compared with usual sunglass lenses, the ProGolf glasses have no light-dimming properties. Instead, they increase the contrast by selective absorption and provide a very good vision for the golfer.
