Aviators flying at high altitude report difficulty in sighting other aircraft. The factors causing this poor air-to air visibility are discussed, particularly the phenomenon of 'empty field' myopia. It is concluded that the correction of the myopia may moderately improve air-to-air vision. An experiment for quantitatively determining the improvement is proposed, and some practical methods of correcting the empty field myopia are suggested. (Author)
