What Is Shingles? (Herpes Zoster)
Shingles is a viral disease caused by the same organism that results in chicken pox. If you are exposed to the shingles virus, you will not contract shingles if you already have had chicken pox, UNLESS your immune system is compromised, in which case you might.
Shingles can affect the eyes, but most often is confined to rash on the lids. However, corneal involvement can be very serious. If you develop a rash (usually painful) and suspect shingles, contact your physician immediately so a med can be prescribed to help lessen the severity of the illness and perhaps decrease the duration and severity of post-infection pain, which can be quite prolonged.
