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;
