This may have been done before but hey I thought I'd show you my glasses mod that has certainly helped me.
The other day I went riding and five minutes up the road I had to stop to adjust my saddle, within seconds of stopping my eye brows are giving off more steam than a boiling kettle and my glasses are near impossible to see out of!
This got my thinking that there surely is a better way of keeping my eye brows cool to stop them steaming my glasses up.
So I took the clear lenses out of my glasses, put some masking tape over the lens, marked and drilled a series of holes across the top of the lens (see picture below).
After doing this I went for a ride and it helped immensely! No steamy glasses!! Throughout the whole ride I had no problems and it was only when I got home, got off my bike and was inside my garage that the glasses steamed up slightly.
Certainly recommended anybody doing this if they suffer too (although I did it to a cheapish set of DHB glasses and wouldn’t recommend anyone takes a drill to a set of £100+ Oakley’s!!)

Oakley actually sell vented lenses for M-frames. Can't afford to try them, mind...
Bob heath visor spray stops misting virtually completely. Rainx not a bad substitute
NBT: I used to have a pair of Oakley Racing Jackets which helped but the yellow lenses on those went weird and Oakley wouldn't repair them so they had to go. 😥
TJ: I also wanted to see if I could improve air to the eye brows as they are the cause to most of my misting or sweat in eye problems!!
I've had M-frames for ten years now. I'm on my fourth frame, have destoryed three and for the cost of a new warranty (was £10 at forst, now it's about £14 think) got a replacement
