Dry eye does not always feel dry. Common signs include burning or stinging, a gritty or sandy feeling, redness, tired eyes by the end of the day, blurry vision that clears when you blink, watery eyes, and discomfort with contact lenses.
Watery eyes can be dry eye too. When the surface of the eye is irritated, it can produce a flood of tears that do not stay on the eye, so it feels wet and dry at the same time.
