My glasses are always fogged up with my mask on. I've tried a few types, none seem to stop this, so I have to choose blurry without glasses, or foggy with them

My glasses are always fogged up with my mask on. I've tried a few types, none seem to stop this, so I have to choose blurry without glasses, or foggy with them on. At bicycle speeds with a mask I'd definitely want / need that helmet.
