Primary Outcome Measures:
  • Limbal Hyperemia (Redness) [ Time Frame: 2 weeks ]
    Subject distribution according to limbal hyperemia scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  • Limbal Hyperemia (Redness) [ Time Frame: 4 weeks ]
    Subject distribution according to limbal hyperemia scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  • Bulbar Hyperemia (Redness) [ Time Frame: 2 weeks ]
    Subject distribution according to bulbar hyperemia scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  • Bulbar Hyperemia (Redness) [ Time Frame: 4 weeks ]
    Subject distribution according to bulbar hyperemia scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  • Corneal Staining [ Time Frame: 2 weeks ]
    Subject distribution according to corneal staining with fluorescein scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  • Corneal Staining [ Time Frame: 4 weeks ]
    Subject distribution according to corneal staining with fluorescein scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

Criteria

Inclusion Criteria:

Subjects must:

  • be existing soft contact lens wearers of the study control lenses
  • require a distance visual correction in both eyes
  • have a contact lens spherical distance requirement between -1.00 diopters (D) and -8.00D in both eyes
  • have astigmatism less than or equal to 1.00D in both eyes
  • be able to wear lenses available for this study
  • be corrected to a visual acuity of 6/9 (20/30) or better in each eye
  • have normal eyes with no evidence of abnormality or disease

Exclusion Criteria:

Subject are excluded for the following reasons:

  • monovision corrected
  • worn lenses extended wear in the last 3 months.
  • require concurrent ocular medication
  • grade 3 or 4 abnormalities
  • grade 3 corneal staining in more than two regions
  • anterior ocular surgery
  • any other ocular surgery or injury within 8 weeks prior to study enrollment
  • abnormal lachrymal secretions
  • pre-existing ocular irritation that would preclude contact lens fitting
  • corneal irregularities
  • Polymethyl methacrylate (PMMA) or Rigid Gas Permeable (RGP) lens wear in past 12 weeks
