Can alcohol consumption cause itchy watery eyes?

Yes: Itchy and watery eyes are signs of ocular allergies that can be relieved by using antihistamine eye drops and avoiding the triggering sources that cause them. Alcohol consumption is not a common cause for this, but some people are more genetically predisposed to such reactions that cause flushing, nasal congestion, runny nose ; eyes, and even itching of mucosal surfaces, such as eyes and nose.
