Lubricant eye drops, which are packaged in traditional multi-use bottles, contain preservatives to prevent microbial growth. Preservative-free lubricant eye drops are commonly packaged in unit-dose vials. These vials are small plastic one-time-use containers.

Oasis TEARS® PF PLUS Preservative-Free lubricant eye drops are packaged in an innovative ophthalmic multi-use bottle that prevents contamination through the use of a patented closing tip, valve and air venting system that prevents microbial entry into the bottle.  This proprietary system keeps Oasis TEARS® PF PLUS sterile for up to 90 days after opening. 

The Oasis TEARS® brand of eye drops deliver instant relief to dry eyes with its adherence and viscoadaptive qualities.
