contact lens Materials & Water Content
tells us there are only 4 catagories:
hi-lo water content
ionic vs. nonionic water
It says that Biomedics55, Acuvue and Acuvue2 are in the same
catagory- "high water content - ionic"
So my guess is I can wear Acuvue or Acuvue2 if I'm already wearing Biomedics55
Acuvues of course ARE "inversion marked" wheras Biomedics aren't, which is THE problem I'm trying to solve!

I think this 4 way classification of lens types is designed to make testing of new lens solutions easier. i.e. a new lens solution need only be tested on one lens from each of the 4 categories to seek approval. It does not mean the lenses within a given category are similar in properties.
