Performance Evaluation of Different Daily Disposable Silicone Hydrogel Contact Lenses

Performance Evaluation of Different Daily Disposable Silicone Hydrogel Contact Lenses

The goal of this study is to compare the performance of two daily disposable silicone hydrogel contact lenses.

This study is a prospective, bilateral eye, double masked, randomized, 1-week crossover, daily wear design involving two different daily disposable lens types. Each lens type will be worn for approximately one week.

Inclusion Criteria:

1. Is between 18 and 35 years of age (inclusively) and has full legal capacity to volunteer;

2. Has read and signed an information consent letter;

3. Self-reports having a full eye examination in the previous two years;

4. Anticipates being able to wear the study lenses for at least 8 hours a day, 7 days a week;

5. Is willing and able to follow instructions and maintain the appointment schedule;

6. Habitually wears soft contact lenses, for the past 3 months minimum;

   1. No more than 1/3 of participants should be habitual wearer of MyDay or MyDay Energys
   2. No more than 1/3 of participants should be habitual wearer of ACUVUE® OASYS MAX 1-Day or ACUVUE® OASYS 1-Day.

7. Has refractive astigmatism no higher than -0.75DC in each eye;

8. Can be fit and achieve binocular distance vision of at least 20/30 Snellen (Available lens parameters are sphere -1.00 to -6.00D, 0.25D steps).

Exclusion Criteria:

1. Is participating in any concurrent clinical or research study;
2. Has any known active ocular disease and/or infection that contraindicates contact lens wear;
3. Has a systemic condition that in the opinion of the investigator may affect a study outcome variable;
4. Is using any systemic or topical medications that in the opinion of the investigator may affect contact lens wear or a study outcome variable;
5. Has known sensitivity to the diagnostic sodium fluorescein used in the study;
6. Self-reports as pregnant, lactating or planning a pregnancy at the time of enrolment;
7. Has undergone refractive error surgery or intraocular surgery.
