Abstract
The technical memorandum reviews the open literature and research reports originating from civilian and military research establishments on the benefits of Blue Blockers (BBs) for target acquisition under various illumination and meteorological conditions. Although subjective reports from fighter pilots have been mainly favorable, all operational evaluations have failed to show any improvement in the visual acquisition of small targets under any atmospheric conditions. Objective experiments have been able to demonstrate the potential usefulness of the BBs for large low contrast target when viewed under flat light conditions. Reports have shown that the effectiveness of BBs was linked to the amount pigments encountered in the macula of the eye- the stronger the pigmentation the less effective the BBs. These results are discussed in relation to fighter and Search and Rescue operations and comments on color confusion, visual illusion and eye protection. Are also included recommendations for the purchase of a future neutral density filter. A detailed bibliography follows the text.
