Hi Betty. This watery eyes thing has hit me too. Not all of the time, but some of the time, and it was explained to me as a mostly post menopausal thing -basically, becoming desiccated (nice) and the wateriness is a response to the irritation of the eye surface being a bit dry - it's a reaction to protect the eye surface.
I thought I might have blocked tear ducts, as I'd had a diabolical cold a few years before, the worst I'd ever had, and I thought maybe the tear ducts had got partially blocked.
I had them probed at the hospital - I was scared,but it was surprisingly OK. That might have made a little bit of difference - I couldn't swear to it - but, all the same, I do sometimes need to use drops now, if my eyeballs are feeling a bit hot and gritty.
Apparently,this is quite common. Funny, isn't it, how you never hear of these things, and then when they happen to YOU, you find that they're 'quite common'?!
