i finally found a pair of goggles that fit somewhat comfortably over my glasses ($20 Scott's at the local motorcycle shop), but it's still not an ideal setup.

has anyone tried this rockgardn prescription goggle insert? supposedly it works w/ any goggle, and it seems pretty cheap. it would open up more goggle options w/o being limited to only OTG specific goggles.
