My left eye has been watering for 4 days now. I have no allergies, and my eye has no burning, itching, or redness to it. I also don't feel any object in?

Blocked duct. Tearing in the absence of any symptoms or redness is likely due to blockage of the tear duct. Go to the ophthalmologist.
See ohthalmologist. If you are not getting better, best see your ophtalmologist for a full evaluation.
