Black occluder

Gallery ref. 08313

Black occluder

Used to carry out the Cover test. The purpose of the test is to assess the presence, direction and extent of any deviation of the visual axes from the orthoposition.
In the phase that investigates the presence of phorias, the cover test is used to evaluate their compensation speed, the fluidity of the fusion recovery movement, as well as the degree of behavioural asymmetry between the two eyes. The person is required to stare at a target (which may be placed far away or at reading distance)
Used in a variety of tests, it ensures the examination of one eye at a time.
