Redness, swelling, itching, and blisters in the eyes — what could be the cause?

Redness, swelling, itching of the eyes, and blisters on the eyelids may be caused by various factors, with the most common being eye infections such as bacterial or viral conjunctivitis, allergic reactions, or herpes virus infection leading to ocular herpes.

When encountering such symptoms, avoid rubbing the eyes, as this may worsen inflammation and potentially spread the infection. Applying a cold compress can help alleviate symptoms; gently place a clean, cold compress cloth over the affected eye to reduce redness, swelling, and itching. Maintaining good eye hygiene by rinsing the eyes with sterile saline solution can help remove secretions and allergens. Adjust lifestyle habits, ensure adequate sleep, and avoid staying up late or overusing the eyes. Take regular breaks and perform eye exercises to relieve eye fatigue.

If symptoms persist or worsen, seek medical attention promptly for diagnosis and treatment by a physician. The doctor may prescribe antibiotic eye drops, antiviral medications, or antihistamines to control inflammation and treat other infections.
