AT VILLAGE EYES OPTOMETRY
Similar symptoms. A different cause.
Allergic conjunctivitis is inflammation of the conjunctiva—the clear tissue covering the white of the eye and lining the eyelids—in response to an allergen. It can be confused with dry eye because both may cause redness, watering, burning and irritation. The two conditions can also occur together.
What may point toward allergy
Itching is a particularly helpful clue. Symptoms often affect both eyes and may include puffy eyelids, watery discharge, sneezing or a runny nose. Pollen, dust mites, mold and animal dander are common triggers. Symptoms alone cannot reliably distinguish allergy from dry eye, infection or other causes of a red eye.
Why the approach to care differs
Dry eye care focuses on the tear film, eyelids and ocular surface. Allergy care also needs to address the allergic response and exposure to triggers. Depending on your findings, your doctor may recommend allergen avoidance, cool compresses, preservative-free lubricants, or an allergy eye drop with antihistamine and mast-cell-stabilizing activity.
Artificial tears can help wash away allergens and support comfort, but persistent allergy symptoms may need additional treatment. Avoid rubbing your eyes. Antibiotic drops do not treat an allergy.
Choose drops thoughtfully
Oral antihistamines may help nasal allergy symptoms but can also worsen eye dryness. Redness-relief drops are not a long-term solution and may cause rebound redness with repeated use. Steroid eye drops require an eye doctor’s prescription and monitoring. Your clinician can help choose a plan when allergy and dry eye overlap.
When to arrange an examination
Persistent or recurrent irritation deserves an eye examination. Significant pain, marked light sensitivity, reduced vision or a red eye while wearing contact lenses warrants prompt assessment rather than assuming it is an allergy.
