I read the post a few threads down about foggy googles. I'm having the same problem. Only I've been swimming for about 3 months and I've used the same pair since I started. The problem is not only constant fogginess, but they just dont seem to fit right anymore. Even when I stop after intervals, and I flush water through them, the second I put them back on they are foggy, I can barely see the lane lines, or the other swimmers in my lane. Is it time to get a new pair?
I have used the Speedo fluid, and it works. It does sound, to me, as though the OP either needs to find a way so those goggles FIT better, or just replace them with a new pair. Do they seal to your face? The goggles should stick on your face for a bit, if you press them on your eyes, even without the use of the strap. If they don't stick like that, very probably they don't have a good seal, and that's important to start with. I doubt any "anti fog" would help if your goggles are not getting a good seal.
