I've heard more often than not to keep both eyes open.
However... I recently attended a class and the instructor made a strong case for using only one eye. (He sounded pretty qualified to me... 21 years in LE, including SWAT, Homicide detective and undercover narcotics. Taught firearms classes for LE/SWAT, competes in USPSA, etc etc etc)
His demonstration showed that past a certain distance, keeping both eyes open and focusing on the front sight, your target doubles in your vision.
To be fair, the distance where this could be a problem seemed to be outside the "normal" ranges for defensive encounters... but still, was an interesting exercise.
Helps if you understand the concept of and know your dominant eye, then it's not as big of a deal.

357 Python has good points about FOV though.
