Abstract : It was suggested that yellow lens spectacles would provide aircrew in defoliation missions with an easier recognition capability in distinguishing treated areas from virgin jungle. Correspondingly, spectrophotometric analyses of filter lenses and photographic transparencies of terrain were made. Also, the yellow Kalichrome C ophthalmic lens during low-level training flights at 500 to 1,000 ft. and at speeds of 450 to 500 kn were evaluated by F-4 pilots.
