I made a pair for 3 dollars at home depot.
Buy a pair of safety glasses that you like.
Buy (or you may already have) electrical tape.
Buy some 200 grit sandpaper.
tape off the part that you dont want to be "foggled" sand the rest of the lenses causing them to become "foggle like". Peel off the part you taped off to reveal a nice defined clean area that has not been "foggled"
You could even make a check ride version with just slightly less foggled area that would go unnoticed to the examiner for that partial panel NDB approach single engine.
