• Optical Glass -
  Made from distortion-free, precision ground and polished optical glass, Serengeti sunglasses give you the clearest image available. Scratch resistant and chemically tempered for strength, each and every lens is drop ball tested with a steel ball to ensure maximum impact resistance. With proper care, Serengeti lenses can last a lifetime.
  
  
• Premium UV Protection -
  Every day your eyes are bombarded by potentially damaging ultraviolet rays from the sun. Many sunglasses filter some UV light, but Serengeti lenses block virtually 100% of UVA and UVB rays, exceeding all government and commercial standards.
  
  
• Spectral Control® Lens System -
  Serengeti's patented Spectral Control® System is a dynamic, ever-adapting "smart" lens technology that works with your eyes to provide the ultimate in comfort and clarity in any situation. Experience it and you'll discover contrast and high definition like you've never known before.
  
  
• Blue Light Filters -
  Blue light waves cause a unique set of vision problems. These shorter wavelengths can't be properly focused by your eyes, creating a phenomenon known as "blue blur". Blue light waves are responsible for "veiling glare" as they scatter off dust and moisture particles in the air. Serengeti lenses block and filter 95% of blue light, virtually eliminating blue blur and the eye strain and fatigue it can cause.
  
  
• Anti-Reflective Coating -
  Anti-reflective coating on back surface to block glare and back reflections.
  
  
• Photochromic Technology - 
  They react to UV light intensity and alter the amount of light allowed through the lens depending on the light conditions.
