Synopsis of Eye Infections

Eye infections occur when harmful microorganisms—such as bacteria, viruses, fungi, or parasites—invade any part of the eye or surrounding tissues. These infections can affect different structures, including the conjunctiva (conjunctivitis), cornea (keratitis), eyelid (blepharitis or stye), or deeper tissues like the uvea or optic nerve. Symptoms vary by type but commonly include redness, swelling, itching, pain, blurred vision, eye discharge, light sensitivity, and tearing.

Bacterial infections (e.g., Staphylococcus aureus, Streptococcus pneumoniae) often cause yellow or green discharge and may require antibiotic drops. Viral infections (commonly from adenovirus or herpes simplex) typically produce watery discharge and may spread rapidly between people. Fungal and parasitic infections are rare but more serious and often affect contact lens users or those with eye trauma.

Most infections are mild and resolve with supportive care, but untreated or severe infections can damage vision or spread. Proper hygiene, avoiding contact lens overuse, and minimizing eye contact with unclean hands or water sources can prevent many cases.

When to see a doctor:
Consult an eye care provider if symptoms persist beyond 2–3 days, worsen, include vision changes, severe pain, or if there is significant swelling, discharge, or light sensitivity. Rapid treatment is essential to prevent complications, especially in corneal infections.

Natural remedies for Eye Infections

Warm Compresses: Soothes discomfort, loosens discharge, and may speed recovery for styes or bacterial conjunctivitis.

Saline Rinse: Gently cleans the eye and flushes out irritants or debris.

Avoid Contact Lenses: Stop wearing them during infection to prevent worsening or spreading.

Good Hygiene: Avoid touching or rubbing eyes; wash hands frequently and don’t share towels or cosmetics.

Cold Compress (for viral infections): May reduce inflammation and itching.
