A common symptom of dry eye is an itching or burning sensation in the eyes. This discomfort occurs because dry eye syndrome typically results from insufficient tear production or poor-quality tears, leading to inadequate lubrication on the surface of the eye. When the eyes lack moisture, the nerves on the surface of the eye become irritated, which causes symptoms such as burning or a gritty feeling. This sensation can be particularly bothersome, prompting individuals to blink more often to try to alleviate discomfort, yet the underlying issue of dryness persists.

Blurred vision may also occur due to dry eye, as the lack of a smooth tear film can affect the clarity of vision, but it is not as specific or direct a symptom as the burning or itching sensation associated with dry eyes. Similarly, pressure behind the eyes and increased sensitivity to light may present in varying eye conditions but are not the primary or most common symptoms directly linked to dry eye syndrome.
