2Treatment groups
Experimental Treatment
Group I: LID#224381, then AOHG MFExperimental Treatment3 Interventions
Lehfilcon A multifocal contact lenses worn first, with lotrafilcon B multifocal contact lenses worn second in pre-determined order. Each study lens type will be worn bilaterally (in both eyes) for approximately 2 days. CLEAR CARE will be used for nightly cleaning and disinfection.
