Eye flu, or conjunctivitis, is an inflammation of the conjunctiva, the clear tissue over the white of the eye and inner eyelid, caused by viruses, bacteria, or allergies. It is characterized by symptoms like redness, itching, watery eyes, and a gritty sensation, and can be highly contagious, spreading through direct or indirect contact. Treatment depends on the cause; viral cases often resolve on their own, while bacterial cases may require antibiotics, and allergic cases are managed by avoiding allergens and using antihistamines.
Symptoms
Redness or pinkness in the white part of the eye
Itching or irritation
Excessive tearing or watery discharge
Gritty feeling in the eye
Swollen eyelids
Sensitivity to light
Discharge (clear or colored)
Causes
Viruses: The most common cause, leading to viral conjunctivitis, which is highly contagious.
Bacteria: Bacterial conjunctivitis is less common but can also occur.
Allergies: Allergic conjunctivitis is not contagious and is triggered by allergens like pollen or dust.
Irritants: Other causes include exposure to smoke, chlorine, or other irritants.
Treatment
Viral conjunctivitis: Often resolves on its own within one to two weeks; focus on symptom relief.
Bacterial conjunctivitis: May require a doctor to prescribe antibiotic eye drops or ointments.
Allergic conjunctivitis: Manage by avoiding the allergen and using over-the-counter or prescription antihistamine eye drops.
Home remedies:
Apply a warm or cold compress for 5-10 minutes to soothe symptoms.
Use over-the-counter artificial tears to relieve dryness.
Gently clean the eye area with a clean, damp cloth to remove discharge.
Prevention
Practice good hygiene: Wash your hands frequently with soap and warm water for at least 20 seconds.
Avoid touching your eyes: If you do touch your eyes, wash your hands immediately.
Do not share personal items: This includes towels, pillowcases, eye makeup, and sunglasses.
Stay home: If you are contagious, stay home from work, school, or daycare to prevent spreading the infection.
