My left eye is constantly watering what could be making just one eye water and not the other I thought that it might be allergies but will that make just one of them do it all the time?Is it anything I can do because this is really getting annoying!!
Something may be making it much drier, forcing the tearing - Go to walmart and get some artificial tears, like Blink or refresh. Use them faithfully and you should see a big difference - if persistent, see your eye Dr.
Allergies can affect just one eye - it could also be dirt, dust, or something else in your eye, makeup in your eye, a scratch on your eye, or a dry tear duct (your eye will water to lubricate it again).
Do you wear eye makeup? It might be the eye makeup you are wearing. When I wear makeup on my eyelids only one of my eyes waters.
could be pink eye. if when you sleep it like crusts up then you should go see a dr.
It may be allergies. I agree with what mandyloo said.
