I had some eye problems, irritation and redness, some years ago.

My doctor recommended a brand, I believe it was called Preferin Liquifilm?

I don't even know if they still make them, but they worked very well, where all the
Usual stuff like Visene or Murine did little to nothing.

I've also heard an advertisement for an all natural brand, something like symillisan?
Again, not sure of the spelling.
