Counter intuitively, watery eyes are one of the more common symptoms of dry eye disease. There are two types of dry eye: the first is where your eyes do not produce enough tears (aqueous deficient) and the second is where your eyes do not produce the right quality of tears (evaporative). When you have evaporative dry eye your tears evaporate very quickly from the surface of your eye because they are missing the oily component which is what keeps the moisture locked in. With this type of dry eye, your eyes tend to over produce tears in an attempt to re-balance their own moisture levels. Unfortunately, while they can produce a higher quantity they often cannot produce a better quality on their own which means that your eyes will continue to lack moisture but will feel constantly watery.
