Serengeti lenses offer the latest in photochromic technology, which constantly lightens and darkens throughout the day to ensure you see every detail.  The Velocity’s lightweight titanium frame is built for speed, yet balances like a feather on the bridge of your nose.  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.
