Performa surface process repels debris and protein deposits and increases comfort for the life of the lens.

  • The lens is bombarded with electrically excited gas molecules that transform the hydrophobic silicone of the lens surface into hydrophilic silicate.
  • Unlike a coating, Performa surface process is inherent in the matrix of the lens so it does not rub off.
  • AerGel silicone hydrogel material combined with Performa surface process controls hydration dynamics and facilitates transport for dehydration resistance.
  • In addition, rounded edge profile facilitates smooth interaction between conjunctival tissue and edge of lens for easy movement and all-day comfort.
