Eye Infections: Types, Symptoms, and When to See a Doctor

Red, itchy, or swollen eyes? You might be dealing with an eye infection. These are common and usually treatable—but ignoring the symptoms can lead to complications. Whether it's from bacteria, viruses, or allergies, here’s what you need to know about keeping your eyes healthy and protected.

👁️ What Is an Eye Infection?

An eye infection occurs when harmful microorganisms (like bacteria, viruses, or fungi) invade any part of the eye or surrounding tissue. This can affect the eyelid, the conjunctiva (the thin layer covering the white part of the eye), or even the cornea.

🦠 Common Types of Eye Infections

1. Conjunctivitis (Pink Eye)

Very common and contagious

Causes redness, discharge, itching

Can be viral, bacterial, or allergic

2. Stye (Hordeolum)

Red, painful bump on the eyelid (like a pimple)

Caused by a bacterial infection of an eyelash follicle

3. Blepharitis

Inflammation of the eyelids

Symptoms include irritation, crusting, and swelling

4. Keratitis

Infection of the cornea

Can cause eye pain, blurred vision, and sensitivity to light

Often linked to contact lens misuse

⚠️ Signs and Symptoms to Watch For

Redness and swelling

Itching or burning sensation

Watery or sticky discharge

Gritty feeling or light sensitivity

Blurred vision or eye pain

🩺 When to See a Doctor

You should consult an eye doctor if:

Symptoms last more than 2–3 days

You experience pain, vision changes, or swelling

The discharge is thick or green/yellow

You're a contact lens wearer with symptoms

💡 Tips for Prevention

Wash your hands before touching your eyes or applying makeup

Avoid sharing towels, pillowcases, or cosmetics

Clean contact lenses properly and don’t sleep in them

Replace eye makeup regularly

Wear protective eyewear in dusty or dirty environments

Final Thoughts

Eye infections can be uncomfortable—but most are treatable with simple care or medication. Catching the symptoms early and maintaining good hygiene are your best defense. If you're unsure about what's causing your symptoms, don’t wait—see a doctor for a proper diagnosis and peace of mind.
