I stocked these for a long time, then got rid of them, then brought them back. I actually really like them, but my biggest headache was that I never knew if they would fit over someone's glasses even if the dimensions seemed like a good match. I hate that so many people had to return them... high on the hassle factor. But we didn't (and still don't) have any other strapless over-Rx options!

What I keep circling back to is:

• For SOME people, they worked great over their glasses, so it's worth trying; and
• They're actually really good on their own. For some people, they provide a better fit and better protection than any of the other "cheap" ones.

Anyway.

Like most goggle type things, they have a gap in the foam at the side that's covered by an earpiece. This gap WILL let in air. For some users, that's okay as it helps prevent fogging. Other users who need a total seal for maximal symptom improvement will end up wanting to plug that gap with some extra foam. (Note that Tranquileyes foam replacement sets are handy for jury-rigging goggly things in general.)

There are no magic answers with moisture chambers - it's trial-and-error, and, honestly, figuring out what your tolerance is for varying degrees of clunky goggly looks.
