Understanding Eye Infections: Causes, Symptoms, and Treatments (Summary)

The eye is a delicate organ prone to infections, ranging from mild irritation to serious vision-threatening conditions. Quick identification and proper care are essential for maintaining eye health.

How Infections Occur:
Germs can enter the eye through dirty hands, airborne droplets, contact lenses, injuries, or the bloodstream—especially in people with weak immune systems.

Common Infections:

1. Bacterial Conjunctivitis (Pink Eye):
   Caused by bacteria, it leads to redness, thick discharge, and mild discomfort. Treated with antibiotic eye drops and hygiene practices.
2. Viral Conjunctivitis:
   Often linked to colds, it causes watery discharge, itching, and swollen lymph nodes. It usually clears in 1–2 weeks with supportive care.
3. Blepharitis & Demodex:
   Chronic eyelid inflammation, often due to bacteria or skin conditions. Symptoms include itching and crusting. Treated with warm cleansing, antibiotics, or tea tree oil if mites are involved.

Conclusion:
Most eye infections are preventable with good hygiene and early care. Contact lens users and those with persistent symptoms should seek prompt medical attention to protect their vision.
