Experimental Treatment

Group I: Oasys MF, then LID233309Experimental Treatment3 Interventions

Senofilcon A multifocal contact lenses worn in Period 1, followed by serafilcon A multifocal contact lenses worn in Period 2, as randomized. The study lenses will be worn bilaterally (in both eyes) during waking hours for at least 10 hours per day, each wear period \[14 days (-0/+2)\]. Study lenses will be removed daily for cleaning and disinfection with CLEAR CARE.
