About this study

Participants were randomized to wear each study contact lenses for 10 days with investigator and participant masking. The participants who are not contact lens wearer at enrollment wore single vision contact lenses for two weeks during the pre-investigation phase to get adapted to contact lens wear.

Who can participate

Healthy volunteers accepted: Yes

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

Inclusion criteria

  • Age 10 to 16 years;
  • Spectacle refraction: -0.75 to -6.00D spherical equivalent, maximum anisometropia 1.25D, cylinder up to -1.00DC
  • Best corrected visual acuity of at least 20/25 in each eye.
  • Parents/guardians and participant have read and understood the Participant Information Sheet;
  • Parents/guardians and participant have read, signed and dated the Informed Consent;
  • Have normal eyes with the exception of the need for visual correction;
  • Be willing and able to adhere to the instructions set in the clinical protocol and maintain the appointment schedule.

Exclusion criteria

  • Ocular anterior segment infection, inflammation, abnormality, or active disease that would contraindicate contact lens wear;
  • Newly prescribed use of some systemic or ocular medications for which contact lens wear could be contraindicated as determined by the investigator;
  • Monocular participants (only one eye with functional vision) or participants fit with only one lens;
  • Subjects with slit lamp findings greater than grade 1 (e.g. edema, infiltrates, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival, anterior segment inflammation) as per ISO 11980, any previous history or signs of a contact lens related corneal inflammatory event (past corneal ulcers), or any other ocular abnormality that may contraindicate contact lens wear at the enrolment visit;
  • History of herpetic keratitis, ocular surgery or irregular cornea;
  • Enrolment of the family members of the investigator, family members of the investigator's staff, or individuals living in the households of these individuals.
