What triggers a herpes simplex eye infection?
If you have been exposed to the herpes simplex virus, it will usually remain dormant (inactive). However, it can be triggered (set-off) by certain factors. This can then cause cold sores and eye infections. Trigger factors include: • having other illnesses or injuries, • exposure to strong sunlight, • having a fever (high temperature), • exposure to cold gass, • stress, and • having your period (in women). Having a weakened immune system can also trigger regular cold sores or herpes simplex eye infections. For example, if you have HIV or are receiving chemotherapy treatment.
