Common Eye Infections: Symptoms, Treatment & When to See an Optometrist
Eye irritation can happen for many reasons—but when redness, pain, discharge, or blurry vision appear, an eye infection could be the cause.
Many common eye infections can be treated quickly and effectively when caught early. However, delaying treatment may lead to more serious complications that can affect your vision.
At RiverCity Eye Care, we help patients identify eye infection symptoms, find relief quickly, and protect their long-term eye health.
Here’s what you need to know about the most common eye infections, symptoms to watch for, and when to seek treatment.
1. Conjunctivitis (Pink Eye)
Conjunctivitis, commonly known as pink eye, is one of the most common eye infections.
It occurs when the conjunctiva—the thin layer covering the white part of the eye and inner eyelid—becomes inflamed.
Common Causes of Pink Eye:
- Viral infections
- Bacterial infections
- Allergies
- Smoke exposure
- Chemical irritants
Pink Eye Symptoms:
- Red eyes
- Itching
- Excess tearing
- Eye discharge
- Crusting around the eyelids
Pink Eye Treatment:
Treatment may include:
- Prescription eye drops
- Cold compresses
- Medicated ointments
- Eyelid cleansing wipes
Good hygiene is especially important because some forms of pink eye are highly contagious.
2. Herpes Simplex Eye Infections
Herpes simplex virus (HSV) can affect the cornea and lead to recurring eye infections.
Without proper treatment, this infection can become serious and impact vision.
Symptoms:
- Eye pain
- Redness
- Tearing
- Light sensitivity
- Blurry vision
- Painful sores around the eye
Treatment:
There is no permanent cure for HSV eye infections, but antiviral medication can help reduce outbreaks and manage symptoms.
Early diagnosis is important to prevent corneal damage.
3. Blepharitis
Blepharitis is inflammation along the eyelids and lash line.
It often develops because of bacteria, clogged oil glands, or skin conditions.
Blepharitis Symptoms:
- Red eyelids
- Swollen eyelids
- Itching
- Burning sensation
- Crusting near eyelashes
Blepharitis Treatment:
Treatment may include:
- Warm compresses
- Eyelid cleansing

- Ongoing eyelid hygiene routines
4. Styes
A stye is a painful red bump that forms on the eyelid when an oil gland becomes blocked.
Stye Symptoms:
- Swelling
- Tenderness
- Red bump on eyelid
- Mild discomfort
Stye Treatment:
Many styes improve with:
- Warm compresses
- Gentle cleansing
Persistent or severe styes may require treatment from an optometrist.
5. Keratitis
Keratitis is inflammation of the cornea and can become serious if untreated.
It’s commonly linked to poor contact lens hygiene but may also be caused by bacterial, viral, or fungal infections.
Causes of Keratitis:
- Improper contact lens use
- Bacterial infections
- Viral infections
- Fungal infections
- Eye injuries
Keratitis Symptoms:
- Eye pain
- Redness
- Blurry vision

Prompt treatment is critical to protect vision.
Treatment may include prescription medicated eye drops depending on the underlying cause.
