What is a common symptom of dry eye syndrome?

A gritty or burning sensation in the eyes is a hallmark symptom of dry eye syndrome. This condition arises when the eyes do not produce enough tears or when the tears evaporate too quickly, leading to dryness and irritation. Patients often describe the sensation as if there is something in their eye, which can be uncomfortable and distracting.

The underlying mechanisms involve the lack of adequate lubrication provided by tears, making the exposed surface of the eye feel scratchy or irritated. This symptom can exacerbate during activities that reduce blinking, such as prolonged screen use or reading, further highlighting the discomfort associated with dry eyes.
