To check that all parts of the eye are working correctly. Often, a field test is only performed where there is a diagnosis or possible diagnosis of field loss. In that case, it would be initially to give a base line assessment: i.e. what are the fields like now, and then it would be repeated over time to assess if there had been any change.

Normal vision in both eyes for right half of the visual field absence of vision in both eyes for left half of the visual field?
Normal vision in both eyes results in the right half of the visual field being dominant. The absence of vision in both eyes results in the left half of the visual field being dominant.
If an object is moving to the left at a constant speed and your eyes are rotating to the left at twice the speed how will you see the object?
The object will appear to be moving to the right in your visual field. This is because your visual field is moving to the left faster than the object is moving to the left. What you will see is that the object will appear in your visual field on the left, and the object will move across your visual field to the right.
