The psychological septum. An investigation into its function.
An experiment was designed that demonstrates that in a state of normal binocular vision a low plus sphere fogging the vision to 6/12 (20/40) produces an inhibition of the central foveal cones in the fogged eye. This inhibition is a natural process that can be switched on and off rapidly so that the fovea receiving the clearer image can examine it and hence produce maximum binocular acuity.
