Serengeti lenses offer the latest in photochromic technology, which constantly lightens and darkens throughout the day to ensure you see every detail.  Duccio is, in every possible meaning of the word, sophisticated.  The design is timeless, the technology cutting edge and the execution is without flaw.  Frame fronts and proprietary Polar Phd lenses are made with lightweight, optically-superior Trivex.  The 555NM lens gets its name from the 555 nanometer center of the visible color spectrum of light, the point where the human eye sees the easiest and most comfortably.  Ideal for bright light conditions, the Photochromic 555nm lens manages yellow and green light transmission to cool and relax the eyes.  The light silver mirror coating further reduces eyestrain by acting as a protective shield against glare.  The Polar PhD lens offers stunning visual acuity and the utmost UVA/UVB protection.  In fact, its as optically close as you can get to a glass lens.  No wonder it won the coveted international Silmo d'Or Award for innovation and performance.  And like all of our lenses, Polar PhD features photochromic, Spectral Control and polarization technology.
