So what I used last night was
Ops drops by McNett - http://www.ukmcpro.co.uk/equipment/eyewear/eyewear-accessories/op-drops-lens-cleaner-anti-fog-detail.html
Bolle Raiders - http://www.bolle-safety.com/tactical-spectacles/raider-raiderkit
The Raiders might look like glasses but they actually come with a prescription carrier that is also a foam seal around the edge, they are thus effectively lo profile and less disturbing to lower face mask googles, although you can certainly use them just as tactical glasses if you wanted.
Played 2 hours in Epsom Bunker, was reasonably cool down there (its still got quite a few puddles after the flooding) and I sweat impressively.
I washed them in soap warm water before heading out, then couple of ops drops on each lens and buffed it in. Between games I just cleaned and reapplied and buffed again. Games were each about an hour long.
