Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Have physiologically normal anterior segments not exhibiting clinically significant biomicroscopy findings (greater than grade 1 and/or presence of infiltrates).
  • Be adapted wearers of soft contact lenses, wear a lens in each eye, and each lens must be of the same manufacture and brand.
  • Be correctable through spherocylindrical refraction to 32 letters (0.3 logMAR) or better (distance, high contrast) in each eye.
  • Be myopic and require lens correction from -0.50 to -6.00 diopters (D) in each eye.

Exclusion criteria

  • An active ocular disease, any corneal infiltrative response or are using any ocular medications.
  • Have worn gas permeable (GP) contact lenses within last 30 days or PMMA lenses within last 3 months.
  • Any Grade 2 or greater finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
  • Any scar or neovascularization within the central 4mm of the cornea.
  • Have had any corneal surgery.
  • Any "Present" finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
  • Any systemic disease affecting ocular health.
  • Using any systemic or topical medications that will affect ocular physiology or lens performance.
  • Currently wear monovision, multifocal, or toric contact lenses.
  • Allergic to any component in the study care products.

Treatment and study plan

Bausch & Lomb Test lens

Device

Lens to be worn on a daily wear basis for one week. Participants will be provided with Bausch + Lomb renu® fresh™ multi-purpose solution for daily rinsing, cleaning, and disinfecting of their lenses.

Ciba Vision soft contact lens

Device

Lens to be worn on a daily wear basis for one week. Participants will be provided with Bausch + Lomb renu® fresh™ multi-purpose solution for daily rinsing, cleaning, and disinfecting of their lenses.

Primary outcomes

  1. Visual Acuity

    Time frame: One week

    The mean difference in high contrast logMAR, over all lens visual acuities (VAs) between lens groups.

Secondary outcomes

  1. Overall Comfort

    Time frame: One week

    The mean difference in comfort-related symptoms/complaints scores between lens groups. Rated on a scale of 0-100 with 100 being the most favorable score.
