Actual (reported)Mean logMAR Contact Lens Visual Acuity
Visual acuity (VA) will be reported as letters read correctly, and the letters read will be converted to logarithm of the minimum angle of resolution (logMAR) acuity. The participant will read rows of letters on a standard LogMAR chart until the participant misses 3 letters on a row with 5 letters. The total number of correct letters will be recorded. A decrease in the number of correct letters indicates a decrease in visual acuity. Acuity will be averaged across visits.
3 months
Proportion of Participants With Slit Lamp Findings Greater Than Grade 2
During an examination of both eyes without lenses, graded slit lamp findings will be assessed for each eye using Grades 0 (none), 1 (trace), 2 (mild), 3 (moderate), and 4 (severe). Using only the non-missing observations from all visits without imputation, each eye will be classified with respect to findings greater than Grade 2 at any visit (Absent or Present). Epithelial edema, epithelial microcysts, corneal staining, limbal Injection, bulbar injection, upper lid tarsal conjunctival abnormalities, corneal neovascularization, and corneal infiltrates will be evaluated.
3 months
Participants will wear Bausch + Lomb kalifilcon A daily disposable contact lenses for at least 8 hours per day at least 5 days per week for approximately 3 months. Participants will be provided with Bausch + Lomb Sensitive Eyes Drops for use as needed during the study and lens cases for return of worn study lenses to the Investigator at the end of the study.
