When tested as specified in 4.8.6.2, the photopic transmittance throughout the cr tical area shall be 11.0% or greater and the scotopic transmittance shall be 2.0% or greater. At point “C“ for the right eye and at point “Cl fo
14、r the left eye of the same visor, these transmittances (i.e. left photopic vs. right photopic and left scotopic vs. right scotopic) shall not differ by more than 10% of the higher of the two values.
