I wear purevision's silicon hydrogels, which seem to be hydrophillic. They allow more oxygen, but become dry, so i haven't be able to wear them for more than 13 hours. I hear that renu disinfects better than optifree, but it isn't comfortable. Which is better overall for silicon hydrogel contact lenses? I got plentifully of corneal ulcers near opt-free making me skeptical of switching back. Yet the renu doesn't have a feeling comforatble.
I've been using the generic publication of the Renu multipurpose for a couple years now. It's worked resourcefully for me.
