Conditions
Brief summary
This study will investigate performance criteria over one week of daily wear to determine if the Study Test contact lens performs equivalently to the comfilcon A contact lenses in terms of subjective ratings and of visual performance. The study test lens was not the final optical design and the study results were not used for the design validation.
Detailed description
This will be double-masked, randomized, bilateral crossover study comparing the Study Test lens against the comfilcon A control lens, each worn over one week of daily wear. The study test lens was not the final optical design and the study results were not used for the design validation.
