Glasses vs Contact Lenses

Question for the runners who can't see good.

Do you run with glasser or contact lenses?

I'm a glasses wearer. I've got an old pair that's pretty beat up that I use when running. Normally not an issue. If they got sweaty I'll wipe them on whatever and keep going. If it's pissing down rain, I can see well enough without them that I'll leave them at home.

But with the cooler weather, I'm finding they fog up making it hard to see. Road runs I'll just go without, but it's the trail runs that I'd like to see where I'm going.

So does anyone have any tips for wearing glasses in less than idea conditions? Or are contacts a good option? I've never worn contacts before.

Keen to hear your thoughts. TIA
