Study Summary
The purpose of this study is to obtain on-eye performance data to inform contact lens product development.
Primary Outcome
Visual acuity (VA) was collected for each eye individually with study lenses in place at a distance of 4 meters using a letter chart. VA was measured in 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.
Interventions
- DEVICE Comfilcon A contact lenses
- DEVICE Lehfilcon A contact lenses
- DEVICE Multi-purpose disinfection solution
