description: A luminance camera based measuring method to determine the partial illuminance values, which are created by special regions of the visual field measured at the eye level was developed. Here regions were chosen to fit illumination of the left and right eye’s lower nasal part of the retina and the illumination of the lower parts of both retinas simultaneously. Standard and nonstandard office lighting scenes were investigated. Data show that more standard like office lighting scenes cause only weak illuminance in the regions of the visual field which are considered as relevant. Lighting of the opposing wall led to much higher illuminance values for these regions. These results emphasize the importance of the direction of light in terms of investigating non-image forming effects.
