What should you know about herpes pink eye?

Herpes simplex virus can affect the conjunctiva, the clear surface covering the white of the eye, and sometimes the cornea at the front of the eye. Symptoms may include one-sided redness, watery discharge, swollen eyelids, discomfort, and sensitivity to light. A blister or sore around the eyelid or face may be present, but it is not required. Herpes-related inflammation can look similar to other forms of conjunctivitis, so appearance alone cannot confirm the cause.

Arrange a GP or eye-care assessment, particularly when pain, blurred vision, or light sensitivity is present. Avoid touching or rubbing the eye, wash your hands after contact, and do not share towels, pillowcases, cosmetics, or eye drops. Contact lenses should stay out until a clinician says they are safe to use again. Do not start leftover antibiotic or steroid eye drops: antibiotics do not treat viruses, and steroid drops can be unsuitable when a herpes infection is suspected.

Seek urgent medical care for reduced or blurred vision, marked pain, strong light sensitivity, a feeling that something is stuck in the eye, or a spreading rash or blisters near the eye. These features can indicate corneal involvement, which needs timely treatment. Emergency help is appropriate if vision changes suddenly or the eye becomes difficult to open.

Ask whether the cornea needs checking, whether antiviral treatment is appropriate, how long to avoid contact lenses, and which symptoms should trigger same-day review.
