Abstract:

There is a loss in duction as the field of view is progressively restricted while holding the light-level constant. This is similar 1 to the loss in stereoacuity which occurs for Navy divers under the same conditions, and 2 to the loss in duction which occurs in the dark. However, introducing a few simple peripheral stimuli into the empty visual field restores the level of duction but not that of stereoacuity. It was desired to know whether in an empty visual field poor duction is not the basis for a decrement in stereoacuity, but rather that other mechanisms produce the loss in both. It is unlikely therefore, that the underwater stereoacuity of Navy divers will be improved by those methods which improve duction.
