When your eyecare practitioner talks about dry eyes they are talking about the surface of your eye drying out and when this happens then the lids rub against the conjunctiva and white of you eye and it is irritating. The eye then reacts by making more tears to wash out what it thinks is causing the irritation. These tears lack oils which would help to lubricate the eye… the tears evaporate and make the surface dry out even more.
