  • Is at least 17 years of age and has full legal capacity to volunteer;
  • Has read and signed an information consent letter;
  • Is willing and able to follow instructions and maintain the appointment schedule;
  • Habitually wears soft contact lenses in daily wear, for minimum of 6-months;
  • Is correctable to a visual acuity of 20/40 or better (in each eye) with the study lenses;
  • Has an astigmatism of ≤ 1.00 D in subjective refraction;
  • Can be fit with study contact lenses with a power between -2.00 and -5.00 DS;
  • Demonstrates an acceptable fit with the study lenses;
  • Habitually wears single vision soft contact lenses for at least 8 hours per day, 5 days a week, and is willing to wear contact lenses for at least 12 hours a day in the study.

You may not qualify if:

  • Is participating in any concurrent clinical or research study;
  • Has any known active\* ocular disease and/or infection;
  • Has a systemic condition that in the opinion of the investigator may affect a study outcome variable;
  • Is using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable;
  • Has known sensitivity to the diagnostic pharmaceuticals to be used in the study;
  • Is pregnant, lactating or planning a pregnancy at the time of enrolment because the associated hormonal changes cause changes in the tear layer which impact contact lens comfort. Verbal confirmation at the screening visit is sufficient;
  • Is aphakic;
  • Has undergone refractive error surgery;
  • Is an employee of the Centre for Ocular Research \& Education;
  • Has participated in the BOXER (i.e. EX-MKTG-107, phases 1 or 2) or BASSET (EXMKTG-113) Study;
  • Has participated in any clinical trials within a week prior to the study.
