Indeed. I’ve certainly seen it and "it happened to me!".  Rigid
permeable lenses for now, at least until there’s a si-hydro multifocal
to try.

For some reason, the new Optix seems a little less susceptible to lipid
deposits, as did Advance (I don’t have a large enough N to really know
on that one.)

It probably is related to water content, as the O2Optix is nominally 33% or
thereabouts.

Silicone-hydrogels are susceptible to lipid spoilation.
