After the BVS has been achieved monocularly the eyes have to be balanced to work together comfortably. This video demonstrates a simple fogging technique used to do this. After this the reading addition was assessed. This fogging method should be done at the end of the sight test so in the case of a thorough cross cyl examination this should be done after the astigmatic correction has been assessed. In the video I was keeping it brief and only did BVS followed by the binocular balancing and reading prescription.
