What is one of the symptoms often reported by patients suffering from dry eye disease?

Blurred vision is a commonly reported symptom among patients suffering from dry eye disease. This occurs because the lack of adequate lubrication and moisture on the surface of the eye can lead to instability in the tear film, causing visual disturbances. When tears evaporate too quickly or are insufficient in quality or quantity, the result can be fluctuating clarity of vision. This symptom can be particularly noticeable during activities that require prolonged visual focus, such as reading or using a computer.

In comparison, while increased tearing may seem like a symptom one might expect from dry eyes, it is typically a paradoxical response to dryness. Additionally, documented infections are not a symptom of dry eye disease but rather a potential complication resulting from insufficient eye lubrication. Persistent headaches do not specifically indicate dry eye disease and can stem from various other conditions.
