I can also verify that is true. My eye doctor told me the same thing.
As long as you take care of the lenses the same way they are as good
as annual lenses. For people like me who really build up protein
quickly , lenses become very uncomfortable, even with constant
cleaning. I buy a few boxes, but not nearly as many as I would if I
purchased what I would ned to in order to follow wearing drections as
described by the mannufacturer.
