Participant Flow
A total of 151 participants (302 eyes) were randomized to receive test contact lenses and 151 participants (302 eyes) were randomized to receive control contact lenses. After two weeks of wearing the first lens type, the participants crossed over to the second lens type for two weeks.

SECONDARY outcome
Timeframe: 2 weeksPopulation: There were 571 eyes in each group assess for this outcome measure.
Symptoms/complaints were assessed on a scale from 0 to 100, with 0 denoting unfavorable symptoms/complaints. Symptoms/complaints were recorded at each post-dispensing visit based on the subject's experience with the study lens worn prior to the visit. The symptoms/complaints parameters were: Burning/stinging upon insertion; Comfort upon insertion, Overall comfort, and Comfort at the end of the day; Ease of handling/insertion, and Ease of handling/removal; Dryness; Itchiness; Redness; Vision; Lens cleanliness; and Overall impression.

SECONDARY outcome
Timeframe: 2 weeksPopulation: There were 600 eyes with non-missing scores in both groups for this outcome measure.
Graded slit lamp findings for each eye, including epithelial edema, epithelial microcysts, corneal staining, limbal and bulbar injections, upper lid tarsal conjunctival abnormalities, corneal neovascularization, and corneal infiltrates were graded for severity on a scale from 0 (No Finding) to 4 (Severe Finding). The outcome measure is any finding \> grade 2, across abnormalities.
