Abstract : Air Force permissible exposure levels were revised using experimental data from rhesus macaque monkeys and the concept of a minimal retinal spot. The ED/50 levels were annotated from the major sources which met the above criteria. ED/50 levels were annotated from the major sources which met the above criteria. ED/50 values reported for extramacular/paramacular exposures were corrected to the macula by multiplying by an experimentally determined average factor of 0.5. In addition, ED/50 values for neodymium exposures were corrected for ocular chromatic aberration to insure application of the data to a minimum retinal spot size and worst case situation. Safety factor considerations and values were examined and discussed for both the visible and near infrared wavelengths, resulting in reduction of existing Air Force permissible exposure levels.
