The frontal eye field lies in the back part of the middle frontal gyrus, near the precentral sulcus, roughly in Brodmann area 8. It controls voluntary, rapid eye movements (saccades) towards the opposite side. It works with the parietal eye fields and superior colliculus to direct gaze.

Starts voluntary saccades towards the opposite side and directs visual attention.
An acute destructive lesion causes the eyes to deviate towards the side of the lesion, because the opposite frontal eye field pushes them unopposed; this usually recovers in days. A seizure here does the opposite, turning the eyes away from the irritated side. The deviation can be overcome by the vestibulo-ocular reflex, which helps distinguish it from a brainstem lesion.
Both eyes deviate towards the side of an acute frontal lesion and away from the side of a frontal seizure.
