Try rewetting agents when you're wearing your cl's and artificial
tears when not. Gas permeable cl's do not have any water
content like soft cl's. Your doc may have been referring to
wetting angle or the dk (amount of oxygen permeability).

Any irritative reaction, from allergies to drying to environmental
factors (ie.wind blowing) can cause this reflex tearing. It does
sound paradoxical, but in simple terms, quelling the irritative
reaction will reduce the amount the reflex tearing. If it's due
to a dry eye, artificial tears will indeed reduce the irritation
(and thus the reflex tearing).

Is there anything that can be done with respect to the watering?  Or is
there a chance that it might go away eventually?  I remember my doc
talking about RGP's with different levels of water absorption - would
this have any bearing?

You mention irritation, but my RGP's feel totally comfortable at this
point.  There doesn't seem to be any correlation between felt
irritation and eye watering.  There is, however, a strong correlation
with wind blowing into my eyes, or even the air from walking quickly
down the hall.  My eyes have always been like that to some extent, but
much worse with the contacts.

It does sound like dry eye and I would recommend any number
of good artificial tear products (I get good results from the gels
such as "Refresh Liquigel") on a regular basis at night and first
thing in the morning.

The tearing you get from irritation from your gas perms is referred
to as "reflex tearing" and has no real association with dry or
non-dry eyes. In fact, one of the classic complaints of a dry
eye patient is of excessive "watering".

For the last few months I've had this thing where the vision in one or
both of my eyes is foggy when I wake first thing in the morning.  I'm
not sure, but which eye is foggy seems to be related to which side I
was sleeping on.  The problem clears in 5 minutes or so, so it's hard
to diagnose.  This morning I put a few lubricant drops in both eyes
right away and it cleared, so I'm thinking dry eye.

Any thoughts on what might have brought this on, and what I can do
about it?  I mentioned it at my last eye exam, but the doc didn't seem
too concerned and suggested drops before bed.  The weird thing is that
I don't think I have dry eyes in general.  Since I got RGP's (about 3-4
weeks ago now), my biggest problem seems to be excessive tearing...
although at times I think I do go dry too.
