Overview
Brief Summary
The purpose of this clinical study is to evaluate the safety and effectiveness of an investigational soft contact lens compared to a commercially available soft contact lens when worn for daily wear and replaced monthly.
Detailed Description
Subjects are expected to attend 6 study visits. The expected duration of study lens exposure is approximately 3 months.

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.
- •Other protocol-specified 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 contact lenses.
- •Monovision contact lens wearers.
- •Other protocol-specified exclusion criteria may apply.
Outcomes
Primary Outcomes
Distance VA (logMAR) With Study Lenses - Completed Eyes
Time Frame: Dispense, Week 1 follow-up, Week 2 follow-up, Month 1 follow-up, Month 2 follow-up, Month 3 follow-up (at least 4 hours after lens insertion at each follow-up assessment visit)
Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters 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 a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned.
