11. Very small differences between images, however, might yield singleness of vision and stereopsis . 12. This established the neural basis for stereopsis . 13. He never experienced losses in subjective best-corrected acuity, color vision or stereopsis . 14. Her book includes reports of further persons who have had similar experiences with stereopsis recovery. 15. The distinction between screening for the presence of stereopsis and a measurement of stereoacuity is valuable. 16. Children whose mothers ate fatty fish during pregnancy developed better stereopsis than those whose mothers did not. 17. Wheatsone also discovered binocular stereopsis , the perception of depth arising from the lateral placement of the eyes. 18. Notably, over 80 % showed stereopsis post-operatively whereas less than 40 % had showed stereopsis before. 19. Notably, over 80 % showed stereopsis post-operatively whereas less than 40 % had showed stereopsis before. 20. Although Wheatstone's discovery of stereopsis supported fusion theory, he still had to account for binocular rivalry.
