[Closed] Glasses and no Contacts

Nikwax visorproof is really good- not perfect but better than any factory coating I've ever used, and a wee bottle will last you forever. There's loads of heath robinson options like washing up liquid, which kind of work but nothing like as good.

(I would much more recommend contacts, though...)

You really don't want to be getting washing up liquid near anti reflective coatings on specs.

My current glasses have quite good venting even at low speeds (Rudy Project Maya) but I also keep them very clean when possible as this makes quite a difference to the onset of fogging up. Oh, and wear a cycling cap to reduce direct rain.
