What happens if allergic conjunctivitis is not treated?

Allergic conjunctivitis is an immune response on the surface of the eye. Ongoing exposure to pollen, dust, animal dander, cosmetics or another irritant can keep that response active. The eyes may feel gritty, burn, water or produce clear, stringy discharge, while rubbing can make irritation and swelling worse.

Symptoms may disturb reading, screen use, sleep or outdoor activities. The condition can occur alongside allergic rhinitis, so a blocked or runny nose and sneezing may continue at the same time. Untreated irritation does not automatically mean an eye infection, but a change in the pattern deserves assessment.

Limit contact with the suspected trigger where practical, wash your hands before touching your eyes, and avoid rubbing them. A cool, clean compress over closed eyelids can ease discomfort. Contact-lens wearers should remove lenses when symptoms flare and ask a clinician when it is appropriate to resume wearing them.

A clinician or pharmacist can discuss allergy medication and whether allergy testing could help identify a recurring trigger. Do not use someone else’s eye drops, and seek advice before using drops that contain a medicine intended to reduce redness.

Arrange medical advice if symptoms persist despite avoiding the suspected trigger, keep returning, or interfere with daily activities. Prompt assessment is needed for eye pain, light sensitivity, blurred or reduced vision, marked one-sided redness, thick discharge, a feeling that something is stuck in the eye, or symptoms after an eye injury or chemical exposure. Facial swelling with breathing difficulty is an emergency.

Ask whether the pattern fits allergic conjunctivitis or another cause of red or itchy eyes, which triggers are worth avoiding, and whether your current eye drops are suitable. You can also ask how to protect your eyes during future flare-ups and whether nasal allergy symptoms need separate treatment.
