Tears can burn your eyes when the surface of the eye is irritated or inflamed. The most common reason is dry eye disease, where the tear film is unstable or too salty, which can trigger a stinging or burning feeling instead of soothing relief.
When tears do not have the right balance of water, oil, and mucus, they can evaporate too quickly. This increases tear concentration and irritates the cornea, the clear front surface of the eye. Inflammation and small changes in the surface cells or nerves can make the eyes more sensitive, leading to burning even with normal tearing.
Some people also experience burning due to underlying inflammation, autoimmune conditions like Sjögren disease, or a type of nerve-related eye pain. In these cases, symptoms may feel stronger than what is seen on exam, and regular lubricating drops may not fully relieve discomfort.
If your eyes frequently burn, feel gritty, or are sensitive to light, an eye specialist should evaluate you. Avoid self-medicating with redness-relief drops, as they can worsen irritation over time.
