  • Has had a self-reported visual exam in the last two years.
  • Is an adapted soft contact lens wearer.
  • Is not a habitual wearer of either study lens.
  • Has a contact lens spherical prescription between +5.00 to -9.00 (inclusive) best corrected visual acuity of 20/30 or better in either eye.
  • Have contact lens prescription of no less than -0.75D of astigmatism and no more than -2.25D in both eyes.
  • Can achieve best corrected spectacle distance visual acuity of 20/25 (0.10 logMAR) or better in each eye.
  • Can achieve a distance visual acuity of 20/30 (0.18 logMAR) or better in each eye with the study contact lenses.
  • Has clear corneas and no active ocular disease.
  • Has read, understood and signed the informed consent letter.
  • Patient contact lens refraction should fit within the available parameters of the study lenses.
  • Is willing to comply with the wear schedule (at least 5 days per week, >8 hours/day assuming there are no contraindications for doing so).
  • Is willing to comply with the visit schedule.

Exclusion Criteria

  • Has a CL prescription outside the range of the available parameters of the study lenses.
  • Has a spectacle cylinder less than -0.75D or more than -2.50D of cylinder in either eye.
  • Slit lamp findings that would contraindicate contact lens wear such as:

  • Neovascularization > 0.75 mm in form of the limbus
  • Giant papillary conjuctivitis (GCP) worse than grade 1
  • Anterior uveitis or iritis (past or present)
  • Seborrheic eczema, seborrheic conjunctivitis
  • History of corneal ulcers or fungal infections
  • Poor personal hygiene
  • Has a known history of corneal hypoesthesia (reduced corneal sensitivity)
  • Has aphakia, keratoconus or a highly irregular cornea.
