PureVision® Lenses Deliver Exceptional Health

PureVision Contact Lenses Deliver Exceptional Health

PureVision® lenses with patented AerGel silicone hydrogel material have overnight corneal swelling equivalent to wearing no lens at all.1

PureVision lenses Dk/t at -3.00D = 112 (non-edge corrected), 101 (edge corrected).

AerGel silicone hydrogel material coupled with Perform surface process delivers:

  • Enhanced wettability and deposit resistance without inhibiting
    oxygen or fluid transport.
  • High oxygen transmissibility for healthy, white eyes.
  • Reduced risk of hypoxic stress to help maintain excellent ocular health.

1 The illustrations represent results from a series of overnight corneal swelling clinical studies of adapted daily wear soft lens patients. For these investigations patients wore conventional hydrogel lenses (Dk/t ranged from 24 to 40), 100% silicone elastomer lenses (Dk/t > 200), PureVision lenses or no lens. A -3.00D lens was used for the overnight corneal swelling lens comparisons. Corneal swelling measurements were made following closed eye conditions for approximately 8 hours).
