I've been known to occasionally develop a case of severe eye trouble at the office. Symptoms are usually brought on by a beautiful fall day or a Friday before a long weekend. I'm not a doctor, but my advice is to leave the office immediately at the first sign of symptoms as this type of eye trouble is particularly contagious and can be easily spread to your co-workers.
Soon after Wright Engineers was founded nearly 25 years ago, chronic Friday afternoon eye trouble among my staff and me "forced" us to close the office at noon on Fridays--a health-promoting practice we've happily kept up ever since.
