Primary Outcome Measures:
  • Cosmetic Appearance Preference [ Time Frame: After 20 minutes of wear ]
    Participant will be asked on a questionnaire, "Which lens do you prefer for looking more natural?" Subject will record on the questionnaire, "Left lens," "Right lens," or "No preference."

Secondary Outcome Measures:
  • Lens Centration [ Time Frame: After insertion and before 20 minutes of wear ]
    Investigator will assess lens centration using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye. Lens centration will be graded on a 5-point scale, with 0 being centered and 4 being severe decentration with corneal exposure.

Enrollment: 151
Study Start Date: October 2011
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: nelfilcon A
Nelfilcon A printed contact lens randomly assigned to one eye, with etafilcon A printed contact lens assigned to the fellow eye for contralateral wear. Lenses will be worn for 20 minutes.
Device: nelfilcon A contact lens with print
Investigational spherical contact lens
Active Comparator: etafilcon A
Etafilcon A printed contact lens randomly assigned to one eye, with nelfilcon A printed contact lens assigned to the fellow eye for contralateral wear.
Device: etafilcon A contact lens with print
Commercially marketed (Singapore) spherical contact lens
Other Name: 1-DAY ACUVUE DEFINE Vivid Style

Detailed Description:
Participants will be asked to evaluate the cosmetic appearance of two different contact lenses worn contralaterally for 20 minutes. No vision or comfort variables will be assessed in this cosmetic appearance and lens fit non-dispensing study.
