never heard of a culture for this only the schirmer eye test for dry eye?
the eye envy has colloidal silver in it which is natural and cuts down on bacteria just like in teeth the bacteria is stinky so any bacteria build up is stinky - i would get the eye envy and use spring bottled water not tap as i have a maltese and they get tear stains and mine does not yet alot of it is genetics and tear ducts that come into play |
