入选标准

  • • Able to read and comprehend English and give informed consent as demonstrated by signing a record of informed consent;
  • Be at least 18 years old;
  • Willing to comply with the wearing and clinical trial visit schedule as directed by the investigator;
  • Have ocular health findings considered to be "normal" and which would not prevent the participant from safely wearing contact lenses;
  • Has vision correctable to at least 6/12 (20/40) or better at distance in each eye with contact lenses;
  • Be experienced at wearing contact lenses.

排除标准

  • • Any pre-existing ocular irritation, injury or condition (including keratoconus and herpes keratitis) of the cornea, conjunctiva or eyelids that would preclude contact lens fitting and safe wearing of contact lenses;
  • Any systemic disease that adversely affects ocular health
  • An active corneal infection or any active ocular disease that would affect wearing of contact lenses;
  • Use of any topical ocular medication during trial with the exception of saline drops ;
  • Use of or a need for any systemic medication or topical medications which may alter normal ocular findings/are known to affect a participant's ocular health/physiology or contact lens performance
  • Eye surgery within 12 weeks immediately prior to enrolment for this trial;
  • Previous corneal refractive surgery;
  • Contraindications to contact lens wear;
  • Participated or currently enrolled in another clinical trial that may have affected vision or ocular physiology within the previous 2 weeks;
  • Be pregnant (formal testing of pregnancy is not required. A participant's verbal report is sufficient);
  • Worn soft contact lenses 2 calendar days or rigid gas permeable/ orthokeratology lenses 7 calendar days prior.
