The strangest symptom of chronic dry eyes that I experience is a form of double vision called “ghosting”. I notice it primarily while driving. The headlights on oncoming cars appear to be two sets of lights, one set slightly above the other. Monocular double vision presents as a “ghost” image, a shadow that overlaps with the primary image. It can affect the left eye, the right eye or both eyes at once. I would love to hear from other people that experience double vision.
