Exclusion Criteria1
- Active ocular infection, inflammation, or clinically significant ocular surface disease (e.g., severe dry eye, pterygium, keratoconus) Uncontrolled systemic disease or use of systemic medications known to significantly affect the tear film, unless on a stable dose for ≥90 days History of refractive surgery (LASIK, PRK, RK) or intraocular surgery (cataract or IOL implantation) Clinically significant ectropion, entropion, or trichiasis Baseline corneal fluorescein staining score >2 in any single zone (NEI/Industry scale) Current monovision or modified monovision contact lens wear Pregnant or lactating participants Participation in another clinical trial within 30 days prior to enrollment

Interventions
Daily disposable multifocal contact lens refit to match the participant's habitual INFUSE One-Day Multifocal power and add level. Worn a minimum of 8 hours/day, at least 5 days/week for approximately 3 weeks. A mandatory \~15-minute equilibration period is required before over-refraction at the fitting visit. Power is finalized at Visit 2 if adjustment is needed; the primary endpoint is assessed after 2 weeks on the finalized prescription.
