Many people have heard of cold sores, yet fewer know they can inflame the eye. When clinicians talk about ocular herpes, they usually mean herpes simplex virus affecting the cornea or surrounding tissues. This guide explains the types, signs, risks, and care pathways in clear language. We aim to help you act sooner and protect your vision.
What Is Ocular Herpes?
Clinicians often call this condition herpes keratitis (corneal inflammation from herpes simplex). It most often stems from HSV-1, the same virus behind oral cold sores. After a first episode, the virus can lie dormant in the facial nerve and reactivate later. Reactivations may be mild or severe, which is why follow-up care matters.
Ocular involvement can range from eyelid or conjunctival irritation to deeper corneal disease. The cornea’s layers—epithelial surface, stromal middle, and endothelial inner layer—respond differently to infection. That’s why examination with fluorescein dye, a slit lamp, and sometimes lab testing guides precise care. For broader management context, see our Herpes Treatment Guide to understand antiviral roles across HSV conditions.
Types of Eye Involvement
Eye herpes presents along a spectrum. Epithelial keratitis affects the corneal surface and classically creates branching “dendritic” staining patterns. This surface form can cause gritty pain, light sensitivity, and tearing. It responds to antiviral therapy, but recurrence risk persists.
Stromal keratitis (deeper corneal inflammation) and endothelial keratitis (inner layer swelling) can impair clarity and focus. These forms can scar the cornea or raise eye pressure if the drainage angle becomes inflamed. Some patients develop iritis or uveitis (inflammation inside the eye), causing ache, light sensitivity, and blurred vision. Timely diagnosis helps target the right layer, reducing long-term haze and glare.
Early Signs and Symptoms
Catching problems early helps protect the cornea’s surface. Watch for burning, tearing, light sensitivity, redness, and a foreign-body sensation. Some people experience a unilateral headache or brow ache, especially when the pupil constricts in bright light. Look for clustered lid blisters or past cold sores, which may hint at reactivation.
Clinicians sometimes document eye herpes early symptoms as surface pain with pinpoint defects that take up fluorescein dye. Later, a branching pattern may emerge, guiding antiviral choices. If redness clusters around the cornea more than the white part of the eye, seek urgent care. Do not wear contact lenses until an eye specialist confirms safety.
How It Spreads and Risk Factors
People often ask, how do you get eye herpes. Most cases arise when HSV-1 from the mouth or nose area reaches the eye through touch, towels, or contaminated fingers. Less often, droplets or close-contact exposure may play a role when active sores are present. Contact lens wear, ocular microtrauma, UV exposure, stress, and illness may trigger reactivation in those previously exposed.
Community prevalence varies, but prior HSV-1 exposure is common in adults. That said, most people never develop corneal disease. Good hand hygiene, avoiding eye rubbing, and pausing contact lens use when sick can lower risk. For a quick refresher on broader symptoms, see our Herpes Symptoms Overview to connect oral or skin outbreaks with eye exposure risks.
Contagious Period and Precautions
People typically shed virus most when lesions are active on the skin, eyelids, or corneal surface. During an outbreak, avoid sharing eye cosmetics, towels, or contact lens supplies. Keep hands clean, and resist touching the eye, nose, and mouth in sequence. Replace contaminated lenses and cases as directed by your eye-care professional.
Many ask how long is eye herpes contagious. Shedding is usually brief and tied to active lesions, though exact timing varies. Avoid kissing infants or immunocompromised people during outbreaks and cover cold sores. For transmission basics and related conditions, see our Infectious Disease Insights for practical prevention principles.
Is It Dangerous? Complications and Vision Risk
Untreated or recurring disease can scar the cornea, distort the surface, and reduce contrast sensitivity. Over time, deep inflammation may raise eye pressure, causing secondary glaucoma risk. Some people develop chronic dry eye from nerve damage after repeated episodes, which can blur vision and increase burning.
Understandably, families ask, is eye herpes dangerous. Most episodes are manageable with care, yet repeated inflammation raises the chance of scarring, haze, and even transplant in severe cases. Discuss driving, screen work, and sports safety with your clinician during active disease.

Rare Brain Involvement and Headache Red Flags
Severe headache, fever, new confusion, or seizures are not typical of routine corneal disease. They require urgent evaluation because the virus rarely spreads to the central nervous system. People sometimes ask how does herpes spread to brain. It can travel along nerves in exceptional cases, resulting in encephalitis. While rare, delays in care can be serious.
When symptoms escalate beyond eye pain—especially with altered awareness—seek emergency assessment. For background on herpes encephalitis, the CDC overview on HSV provides general context, and NINDS information on encephalitis covers neurological warning signs. These sources help distinguish routine eye inflammation from rare neurological emergencies.
Diagnosis and Testing
Eye clinicians diagnose herpes keratitis with a slit-lamp exam and fluorescein dye to highlight surface defects. Dendritic or geographic patterns can suggest viral activity. In atypical cases, a clinician may gently swab the eye to run PCR (a lab test that detects viral DNA). Imaging is uncommon but may be used to assess complications.
Because some corneal disorders mimic herpes, a careful history matters. Prior cold sores, stressors, contact lens use, and topical steroid exposure can guide thinking. The American Academy of Ophthalmology guidance outlines examination features and cautions, including the careful use of steroids in deeper forms under specialist supervision.
Treatment Overview
Clinicians tailor eye herpes treatment to the layer involved. Surface disease often responds to antiviral therapy and supportive lubrication. Deeper inflammation may require carefully supervised steroid drops alongside antivirals to protect the cornea and control immune-driven swelling. Pain control, light avoidance, and safe activity guidance help during recovery.
Antivirals can be topical or oral, depending on severity and location. Your clinician may consider suppressive therapy if recurrences disrupt vision or daily life. For medication background, see Acyclovir Antiviral for product labeling details and Famciclovir Antiviral for dosing considerations discussed between you and your prescriber.
Topical and Oral Medicines
Clinicians sometimes prescribe antiviral eye drops for herpes or antiviral gel to target surface replication. Oral agents can help both surface and deeper layers, especially when eyelids or inner eye structures are inflamed. Lubricating drops and ointments support healing by reducing friction and dryness-related pain.
Antibiotic drops are not antiviral; however, they may be used if a secondary bacterial issue is suspected. Contact lens wear is paused to reduce friction against the cornea. For related dryness topics discussed in chronic eye conditions, see Xiidra Eye Drops for rationale on managing surface irritation after inflammation resolves.
Steroids: Why Caution Matters
Topical steroid drops can help with stromal inflammation, but they must be used with antiviral coverage and specialist oversight. Using steroids in untreated surface disease may worsen viral replication and deepen the lesion. That is why precise diagnosis guides whether and when steroids are introduced.
Follow-up visits allow dose adjustments and checks for eye pressure changes. Discuss any background glaucoma, previous steroid responses, and allergy history. If you are ever uncertain about a bottle or label, bring all drops to the appointment for review.

Prevention, Triggers, and Everyday Care
Prevention starts with clean hands, avoiding eye rubbing, and pausing contact lenses at the first hint of redness. Replace makeup and lens cases after outbreaks. Address triggers like stress, dehydration, sun exposure, and illness where possible. Sunglasses can reduce light sensitivity during recovery.
Some patients benefit from longer-term antivirals to reduce recurrence risk. This strategy is individualized and reassessed over time. For household safety, avoid sharing towels and cosmetics, and cover active cold sores.

Children, Contact Lenses, and HSV-2 Considerations
Children may rub eyes when they have cold sores or respiratory illness, seeding the virus onto irritated surfaces. Caregivers should wash hands often and clean toys that contact the face. For pediatric prevention tips around vision protection, see Children’s Eye Health for age-appropriate safety steps.
HSV-2 can rarely involve the eye, including from neonatal exposure or adult contact. Early involvement may mimic other red-eye problems, so careful examination is essential. For complete HSV context, see Genital Herpes Symptoms to understand how different HSV types behave and when clinicians consider targeted testing.
Contagion Myths, Photos, and Self-Diagnosis
Looking up images can help you understand patterns, but every eye is different. Lighting, skin tone, and camera focus all change how lesions appear. Use curated resources judiciously, and do not delay care while comparing ocular herpes photos found online. If you wear contact lenses, store them safely and avoid reuse during any red-eye episode.
It is natural to worry about spread to loved ones. Focus on practical steps: handwashing, not sharing linens, and covering any cold sores. For eye-health context that supports safer routines, see our Vision Changes With Age overview for habits that protect the ocular surface over time.
When to Seek Care
Urgent evaluation is warranted if you notice severe light sensitivity, sudden blur, deep eye ache, or a new white spot on the cornea. Seek emergency care for fever, confusion, or stiff neck with eye pain. Timely care protects vision and reduces complications. Parents should be especially cautious with infants and immunocompromised family members.
Tip: Bring your contact lenses, cases, and all eye drops to appointments. This helps your clinician check for contamination, contraindications, and proper instructions.
