With the caveat that someone might know of a specific exception, and that you should always be careful about buying generic "Paintball airsoft motorcycle adventure military action sport hobby fancy dress" gear from eBay or Amazon: yes.

(Legit) paintball masks are full face, full seal, and have to withstand higher energies than airsoft specific gear.

I use a Valken Annex MI-7 paintball mask with dual pane lenses that's commendably resistant to fogging.  DYE branded masks are particularly well regarded.

Thanks, my paintball playing mate wants to have a go but wants to use his own eye pro.

Ah, right, then yes, he'll be fine.
