Yep, Colin P, I've read this while I was reading up about ocular immunology. That the immune system is supposed to prompt a bit of a takeover maintaining the tear film and protecting the eye surface during sleep while we're not blinking. Obviously a protective tear film is not just tear from the eyelids but is supposed to be replenished through the eye surface as well. I'll post a reference if I ever find it again.
That we dont produce tears at night, simply because we dont need to?
Also read, Jenny, that prompts affect both eyes (eg where there is a vision problem in one eye, not your case), so maybe if one is suffering dry then it may be overprompting the other to tear. Just guessing.
