| Abstract: |   Technologies pertaining to determining when glare will be perceived by a
     hypothetical observer from a glare source and the intensity of glare that
     will be perceived by the hypothetical observer from the glare source are
     described herein. A first location of a potential source of solar glare
     is received, and a second location of the hypothetical observer is
     received. Based upon such locations, including respective elevations, and
     known positions of the sun over time, a determination as to when the
     hypothetical observer will perceive glare from the potential source of
     solar glare is made. Subsequently, an amount of irradiance entering the
     eye of the hypothetical observer is calculated to assess potential ocular
     hazards. |
