After completion of monocular subject refraction, binocular balancing is performed to balance the state of accommodation between two eyes. Binocular balancing aims to balance the state of accommodation of the two eyes. The procedure ensures that a person exerts the…
The prism dissociation and alternate occlusion test are only used when both eyes have similar monocular visual acuity. If monocular corrected visual acuity is not the same for both eyes, the bichrome prism dissociated method is used. Procedure of bichrome…
This differs from the vertical prism dissociation method, instead of using prisms in both eyes, eyes are dissociated using occlusion. A paddle occlude is used for occlusion of the eye (occluder which is used in the cover test) which allows…
The procedure makes use of prisms to break the fusion between two eyes. The vertical prisms of the same amount are used to maintain equal degradation of image quality which is caused by prism. Don’t use horizontal prisms, as a…
