FRESHKOTE® Preservative Free (PF) offers nurturing and long-lasting relief from dry-eye symptoms. Its unique, preservative-free formula supports all three layers of your tear film — the mucin, aqueous, and lipid layers — helping to keep your eyes moist and comfortable, even with contact lenses. The active ingredients (polyvinyl alcohol 2.7% and povidone 2.0%) ensure full wetting of the ocular surface and reduce tear evaporation, while its multi-dose bottle with a closure tip delivers sterile drops without preservatives. Experience soothing relief from irritation, burning, or itching caused by dryness, wind, and sun
