What causes redness in a child's eyes?

Redness in a child's eyes may be caused by eye rubbing, foreign body entry, lack of sleep, conjunctivitis, or blepharitis. It can be improved by avoiding eye rubbing, cleaning the eyes, getting sufficient sleep, and using medication if necessary. If symptoms are accompanied by pain, increased discharge, or persist over time, prompt medical attention is required.

1. Eye Rubbing Irritation: Frequent eye rubbing with dirty hands can introduce bacteria or cause mechanical irritation to the conjunctiva, leading to red eyes. It is recommended to prevent this behavior immediately, clean the hands with a sterile wet wipe, and no special medication is needed if no other abnormalities are observed in the eye.

2. Foreign Body in the Eye: Dust, lint, or other foreign objects entering the eye can irritate the conjunctiva, causing redness and possibly accompanied by blinking or tearing. It is advised to rinse the eye with sterile saline solution or gently remove the object with a clean cotton swab, avoiding forceful rubbing.

3. Sleep Deprivation: Staying up late or poor sleep quality can impair ocular blood circulation, resulting in conjunctival congestion and red eyes. It is recommended to maintain regular sleep habits, ensure adequate daily rest, reduce screen time, and apply a warm towel compress around the eyes to relieve discomfort.

4. Conjunctivitis: Inflammation caused by bacterial or viral infection of the conjunctiva leads to redness, increased eye discharge (eye boogers), and itching. Under a doctor’s guidance, medications such as tobramycin eye drops, erythromycin eye ointment, or acyclovir eye drops may be used to alleviate symptoms.

5. Blepharitis: Bacterial infection at the edge of the eyelid causes redness of the eyelid margin and surrounding conjunctiva, often accompanied by itching and easy loss of eyelashes. Patients may use medications such as chlortetracycline hydrochloride eye ointment, tobramycin eye drops, or cefaclor dry suspension under medical supervision to relieve symptoms.

Maintain good eye hygiene by gently wiping away secretions with clean cotton swabs, avoid sharing towels or washbasins, eat a light diet rich in fruits and vegetables, drink plenty of water, avoid prolonged eye strain, and protect your child's eye health.
