This SAE Recommended Practice establishes methods for describing and measuring the driver's field of view. The document describes three methods for measuring the direct and indirect fields of view and the extent of obstructions within those fields. The first method uses any single pair of eye points to determine the fields or obstructions that would be seen by an individual driver. The second method uses the SAE Eyellipses defined in SAE J941 to determine the largest fields or obstructions that would be seen for a given percentage of the driving population. The third method uses specific eye points defined in SAE J941 to measure the extent of a specific field of view or obstruction for which those points were developed.

This SAE Recommended Practice establishes two-dimensional eye ranges, representative of 90th, 95th, and 99th percentile increments* of the driving population, for use in defining the driver's visual requirements to interior and exterior environments in passenger cars. It is to be used in conjunction with the two-dimensional manikin specified in SAE J826. Definitions of the interior dimensions used in this SAE Recommended Practice are listed as an appendix to this practice and are quoted from Section E1 of the SAE Aerospace-Automotive Drawing Standards. Reproductions of the passenger car driver's eye range contours may be obtained from SAE by ordering eyellipse drawings supplementary to SAE J941.
This SAE Recommended Practice describes methods for determining total and specular reflectance for mirrors with flat and curved surfaces and a method for determining diffuse reflectance and haze for mirrors with flat surfaces.

The design and location of rear-viewing mirrors or systems, and the presentation of the rear view to the driver can best be achieved if the designer and the engineer have adequate references available on the physiological functions of head and eye movements and on the perceptual capabilities of the human visual system. The following information and charts are provided for this purpose. For more complete information of the relationship of vision to forward vision, see SAE SP-279.
