- Inform patient, "I'm going to be checking your side/peripheral vision with this test. While staying focused on my eye, tell me how many fingers I'm holding up. It'll be either 1, 2, or 4."
- Ask patient to remove spectacles
- Stand 60 cm away facing the patient
- Using an occluder, ask patient to cover their left eye

- Hold up 1, 2, or 4 fingers in the periphery in one of the 4 quadrants (superior temporal, superior nasal, inferior temporal, inferior nasal).
- Have the patient tell you the number of fingers they see. Make sure they are focused on your open eye and do not look at your hand.
- Check the remaining 3 quadrants.
- Repeat confrontation visual fields for the other eye. Ask patient to occlude their right eye and focus on your right eye (be sure to close your left eye).
