Hello and thanks for your question.
You are correct in thinking that this rash might be herpes. A herpes rash is classically these little whitish "bubbles" or vesicles that are on a base or reddened skin.
Because herpes viruses can affect the eyes in such profound ways, I would suggest you see an ophthalmologist as soon as you can to start treatment if you have any eye problems from it.
Does that help address your concerns?
