New Gas Permeable lenses: "foggy" vision

Hi,

I am two weeks into wearing RGP lenses. They are getting more and more
comfortable, but one proble keepps recurring. In my left eye, I have
the sensation of slightly foggy vision, it comes and goes but always
seems to be there to some extent. My left lens is also less
comfortable than the right. What is causing this? What can I do about
it?

Thanks in advance,

dan
