I use ESS goggles and I generally get new glasses every 6 - 12 months because of minimal increments in sight and this what I did using an old pair of glasses after a .1 change in sight. Don't know if you would be willing to clip some old glasses but I sure was.
Then they jam on either side of the goggles like this. (ESS NVGs and they also work in the TurboFans)
I do plan on dremeling some wooden inserts because I get the occasional angle mis-misalignment.
The only reason I fog up is because I sweat but I've started focusing on controlling how much I sweat
