I'm using contacts for 10 years and never had this problem but since thel ast two days, one eye waters a lot in 15 minutes of inserting the lens and going out in the sun(not much discomfort while indoors but still there is some discomfort).It gets read and watery to the point that i have ti pull out the lens.
I haven't over used lenses, I actually use it just for 5 hours a day and never sleep in them. I use clean hands to insert and remove.
>>> One eye is geting watery with contacts?
