What Is Eye Herpes?
Eye herpes, also known as ocular herpes or herpes simplex keratitis, is an infection caused by the herpes simplex virus (HSV). It's the same virus responsible for cold sores, except in this case, the infection affects the eyes.
Most people contract HSV-1, which commonly causes oral cold sores. But once the virus is in the body, it can lie dormant and reactivate later — sometimes affecting the surface or even deeper layers of the eye. Unlike other eye conditions that heal with simple care, ocular herpes tends to come back. That’s why it's considered a chronic condition, even if symptoms disappear for a while.
How Does It Affect the Eyes?
Ocular herpes can impact several parts of the eye:
- Cornea (the clear front surface of the eye): This is the most common site of infection.
- Conjunctiva (the thin layer covering the white part of the eye).
- Eyelids and surrounding skin can also be involved, especially during a first outbreak.
When only the outer layer of the cornea is affected (called epithelial keratitis), it can heal without scarring. But if the virus gets into deeper layers, it can lead to stromal keratitis — a more serious form that may cause permanent vision damage if not treated correctly.
Common Symptoms of Eye Herpes
Symptoms may appear suddenly and can mimic other eye infections or allergic reactions. The most common include:
- Redness in one eye
- Eye pain or a gritty sensation
- Tearing or watery discharge
- Blurred vision
- Light sensitivity
- Swelling around the eye
- A feeling like there’s something in your eye
- In more severe cases, visible sores on the eyelid or cornea
If these symptoms show up and don't go away within a day or two — especially if you’ve had a cold sore recently — you should reach out to our eye care team right away. Waiting can increase the chance of lasting damage.
What Causes Eye Herpes Flare-Ups?
The tricky part about herpes is that once you have the virus, it stays in your body for life. It can reactivate — especially during times when your immune system is compromised or your body is under stress.
Common triggers include:
- Stress or illness (like a cold or flu)
- Sun exposure, particularly UV light
- Eye trauma, including rubbing your eyes too hard
- Fever or fatigue
- Hormonal changes, like those during menstruation
- Eye surgery or contact lens use, in rare cases
Because flare-ups can’t always be predicted, it’s helpful to be aware of your body’s signals — especially if you’ve had eye herpes before.
Can Eye Herpes Be Prevented?
While there’s no way to completely prevent eye herpes, you can reduce your risk of flare-ups and limit how often the virus affects your eyes. Here are a few helpful tips:
- Avoid touching your eyes, especially if you have a cold sore or are feeling run-down.
- Wash your hands regularly, particularly if you’re sick or handling contact lenses.
- Protect your eyes from sunlight with UV-blocking sunglasses.
- Manage stress with exercise, sleep, and support — emotional stress can weaken your immune system and prompt a flare-up.
- Talk to your eye doctor if you’ve had eye herpes before. In some cases, long-term antiviral medication may be recommended to prevent recurrences.
If you’re prone to flare-ups, keep track of what seems to trigger your symptoms and mention this at your next eye exam. The more we know about how your body reacts, the better we can help you stay comfortable and clear-eyed.
Eye Herpes Treatment in
If you’re experiencing symptoms of eye herpes — or think it might be something more than pink eye — the best thing you can do is call your optometrist right away. Prompt treatment is the key to preventing long-term vision problems.
At , our team uses advanced diagnostic tools to examine the surface and deeper structures of the eye. If we find signs of herpes, we’ll start treatment quickly. Most mild cases can be managed with prescription antiviral eye drops or oral medication. For more serious cases, especially those affecting the cornea, corticosteroid drops may be added to reduce inflammation — but only under close supervision.
We’ll also create a plan for managing your long-term eye health and minimizing future outbreaks. Even if your symptoms fade, it’s still essential to monitor the health of your eyes regularly. Every case is different, and we want to make sure you’re not at risk of scarring or vision loss later down the line.
Quick Q&A: Eye Herpes Edition
Can I spread eye herpes to someone else?
Yes — HSV-1 is contagious, especially if you have an active cold sore or eye sore. Avoid touching your face, and wash your hands thoroughly if you do.
Is eye herpes the same as pink eye?
No. While they can look similar, pink eye (conjunctivitis) is usually caused by bacteria or allergens and isn’t related to the herpes virus.
Do I need to stop wearing contacts if I have eye herpes?
Yes — at least temporarily. Contacts can make symptoms worse. Your doctor will let you know when it's safe to resume.
Can I get eye herpes more than once?
Yes. Like cold sores, eye herpes can recur. That’s why working with an optometrist is important — we’ll help you manage it if it comes back.
