Pfizer -
Visine Uni-Dose* Advance True Tears in a
"one-click, one-drop" technology Preservative Free
Bottle
A new version of Visine is now
available in North America in a preservative-free container. In its
Canadian website, the new Visine is presented in this new formulation
without benzalkonium (as opposed to the majority of the Visine line).
The website mentions that "Preservatives contained in multi-dose
bottled products have been shown to be sensitizing to some individuals".
Actually, to consider the preservative problem as a sensitization
problem means eluding part of the problem and notably the cytotoxic and
tearfilm disruption effects of preservative. However, we salute this
effort since it's "the only preservative-free
formula on the market in Canada that comes in a multi dose bottle."
Unfortunately, most of the Visine line remains preserved with
benzalkonium. Finally, let's say that product is in fact a multi-dose
container and the company chose the misnomer of Uni-dose to name it! In
doing so, Pfizer reveals itself as a beginner in matters related to
preservative.

This is what we call the 'Preservative Paradox!
Preserve
our Eyes, not our Drops!
