Dry eye can cause burning, irritation, a gritty feeling, or blurred vision. It may occur when the eyes do not produce enough tears or when tears evaporate too quickly. Symptoms and causes vary, so a home measure may not address every case.
Notice patterns and possible contributors
Track when symptoms occur—for example, during screen use, in air-conditioned rooms, or after starting a medicine. Health conditions, the eye’s tear film, environment, and medications can all matter. Do not assume a symptom has one cause or stop a prescribed medicine without speaking with the prescriber.
Care and when to get help
Discuss suitable lubricating drops or other treatments with an eye-care professional or pharmacist, particularly if you use several medicines or have an existing eye condition. Arrange an assessment if symptoms recur, persist, or do not improve. Severe eye pain, sudden blurred vision, or a change in vision needs prompt professional assessment.
