Why Dry Eye Disease Traps Millions in a Cycle of Pain and Inflammation

Dry eye disease (DED) affects millions worldwide, causing persistent discomfort and irritation. The condition occurs when the eyes fail to produce enough tears or when tears evaporate too quickly. In the US alone, around 33 million people have been diagnosed, with another 6 million experiencing symptoms without a formal diagnosis.

DED is particularly common in those over 50, though younger individuals can also develop it. People assigned female at birth face double the risk compared to those assigned male. Certain factors, such as wearing contact lenses, further increase the likelihood of developing the condition.

Autoimmune disorders, including rheumatoid arthritis and thyroid disease, are also linked to a higher risk of DED. The disease often triggers inflammation, which worsens symptoms and creates a painful cycle. Damage from dryness prompts the immune system to respond, leading to redness, burning, and a gritty sensation.

Once inflammation sets in, it can make the eyes even drier. This creates a loop where dryness causes more inflammation, and inflammation worsens dryness. The result is ongoing discomfort, often described as feeling like a foreign object is in the eye.

DED remains a widespread issue, with millions suffering from its effects. While treatments exist, managing inflammation is key to breaking the cycle of discomfort. Early recognition of symptoms, such as redness and irritation, can help prevent the condition from worsening over time.
