Pilla Performance Eyewear has developed a highly technical lens technology to address a very simple need: Perfect vision for sport. Enhanced Color and Contrast Pilla uses a proprietary high definition technology called ColorTrast in all our lenses: both prescription and nonprescription. The technology intensifies color and increases contrast to produce extremely sharp detail and color registration. Combined with our Ballistx lens material, we achieve crystal clear optics with significant performance advantages for Shooting Sports, as well as many vision critical sports. Whether you are shooting clays or hunting game, the performance is superior. The Key to our crystal clear Optics starts with manufacturing process. Perfect Vision Most lenses used for sports are Polycarbonate, resulting in vision which is not crisp. Manufacturing processes of Polycarbonate lenses are completely different from our world renowned Ballistx lenses. Pilla lenses offer: 100% UV Filter from the Suns Harmful UV Rays Glass Molds (not metal injection) Hand Crafted Longer Dry Time Slow Cured Without Heat or Cooling Superior Scratch Resistance Perfect VISION is critical for maximum performance in sport.
