This exam might also be known as a perimetry, Automated perimetry exam, Tangent screen exam, Goldmann visual field exam and Humphrey field exam. A test of this kind may be given by a technician, a technician with help from a machine, or just a machine.

There are even tests specifically designed to assess health of the eyes. A doctor consultation is the best way to find out what exams to take, what the results mean, and the steps to take based on those results.
