Dry eye is a common condition that may be caused because your eyes do not produce enough tears, or because the tears that you have evaporate too quickly or do not spread evenly across the front of your eye. The symptoms are usually in both eyes.
Dry eye can make your eye feel scratchy or irritated. In severe cases it may temporarily make your vision blurry. It can be uncomfortable, but rarely causes serious eye damage.
