Overview
Brief Summary
The purpose of this clinical study is to evaluate the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in a daily wear modality.
Detailed Description
Subjects will be expected to attend 4 office visits: Screening/Baseline/Dispense, Week 1 Follow-up, Month 1 Follow-up, and Month 3 Follow-up/Exit. The total expected duration of participation for each subject is approximately 3-4 months in this daily wear clinical study.

Eligibility Criteria
Inclusion Criteria
- •Successful wear of spherical daily wear frequent replacement soft contact lenses for distance correction in both eyes during the past 3 months for a minimum of 5 days per week and 8 hours per day;
- •Manifest cylinder equal to or less than 0.75 diopter (D) in each eye;
- •Best spectacle corrected visual acuity (using manifest refraction) of 20/20 or better in each eye;
- •Other protocol-defined inclusion criteria may apply.
Exclusion Criteria
- •Wearing habitual contact lenses in an extended wear modality (routinely sleeping in lenses for at least 1 night per week) over the last 3 months prior to enrollment;
- •Habitually wearing Biofinity lenses;
- •Monovision or multifocal contact lens wearers;
- •Other protocol-defined exclusion criteria may apply.
Outcomes
Primary Outcomes
Least Squares Mean Contact Lens Corrected Distance Visual Acuity (CLCDVA) at Week 1 Follow-Up
Time Frame: Week 1 Follow-Up
Visual acuity (VA) was assessed for each eye individually with study lenses in place using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with lower logMAR values indicating better visual acuity.
Secondary Outcomes
- Percentage of Subjects Achieving CLCDVA 20/20 or Better in Each Eye at Week 1 Follow-Up(Week 1 Follow-Up)
