This is a practical tool for testing motor ocular dominance at various distances. It is based on the principle by which, under suitable environmental conditions, the brain is forced to prefer one eye (dominant) for alignment of the visual axis over the other. 

Distance Detection - The patient is asked to hold the Mirror Test at arms length whilst observing a spot of light projected through the hole in the Mirror Test. The eye which causes the light to disappear is the dominant eye. 

Near/Proximal Detection - The patient is asked to hold the Mirror Test at about 40 cm away from his/her eyes and asked to observe the tip of his/her own nose reflected in the small round mirror on the Mirror Test. The eye which causes the tip of the nose to disappear is the dominant eye. 

Objective Method - The patient is asked to hold the Mirror Test at arms length and view the examiner’s face through the hole in the mirror test. The examiner can identify which is the dominant eye as there will be a view of only one eye beyond the test hole when the patient can view his face. 

The Mirror Test can be used to check the centration of multifocal lenses.
