To evaluate the performance of two monthly replacement silicone hydrogel contact lenses in habitual FRP CL wearers when worn for 1-month.

This study will be a prospective, randomized, double-masked, single-site, 1-month cross-over design involving bilateral eye daily wear of two different monthly replacement CL types. Each lens will be worn bilaterally for approximately one month.

Inclusion Criteria:

1. Is at least 17 years of age and has full legal capacity to volunteer;
2. Self-reports having had a full eye examination within the previous 2 years;
3. Has read and signed an information consent letter;
4. Is willing and able to follow instructions and maintain the appointment schedule;
5. Is a habitual wearer of frequent replacement contact lenses;
6. Anticipates no difficulty wearing the contact lenses for 6 days/week and 8 hours/day during the study;
7. Has refractive astigmatism no higher than -0.75DC in each eye;
8. Can be successfully fit with both study lens types;
9. Achieves at least 0.4 logMAR VA monocularly and at least 0.2 logMAR VA binocularly with each study lens type.

Exclusion Criteria:

1. Is participating in any concurrent clinical research study;
2. Has any known active ocular disease and/or infection;
3. Has an unstable systemic condition that in the opinion of the investigator may affect vision or contact lens comfort across the 2-month study duration;
4. Is using any systemic or topical medications in an irregular routine that in the opinion of the investigator may affect vision or contact lens comfort across the 2-month study duration;
5. Has known sensitivity to the diagnostic sodium fluorescein to be used in the study;
6. Is an employee of the Centre for Ocular Research & Education.

From dispense up to one month on each study lens, for total of two months
