Re: Red eye
Tears contain lysozymes (enzymes that tear down and destroy the cell wall of bacteria and I just read viruses too, although I'd want to read more to be sure). So bathing the eye in tears would be a good thing to fight off infection. I also recall learning in med school that emotional tears contain higher amounts of lysozymes (as opposed to just lubricating tears).
As for crying increasing intraocular pressure....the IOP fluctuates with the rise in venous pressure caused by crying and straining ... I've been trying to find more data on this, but I would think a gentle cry...would do little to increase the eye pressure. An intense cry, may have a noticeable effect on the pressure.
I will have to spend some time researching this....it'd be good to know.
