- •Able to be fit with contact lenses within the available range of sphere, cylinder power, and axes (based on lens availability).
- •Best Corrected Visual Acuity (BCVA) better than or equal to 0.10 (logMAR) in each eye.
- •Willing to stop wearing habitual contact lenses during in-office visits.
- •Other protocol-defined inclusion criteria may apply.
排除标准
- •Current spherical, monovision or multifocal lens wearer.
- •Protocol-specified biomicroscopy findings at screening.

- •Participation in a clinical trial within the previous 30 days or currently enrolled in any clinical trial.
- •Other protocol-defined exclusion criteria may apply.
结局指标
主要结局
Distance VA with study lenses
时间窗: 30 mins (± 15 mins), each product
Visual Acuity (VA) will be assessed using letter charts with study lenses in place and reported in logarithm minimum angle of resolution (logMAR). A logMAR value of 0.0 equates to 20/20 Snellen, which is considered normal distance eyesight. Eyes will be assessed individually.
