One or more levels of maladaptation are calculated relative to frames of media content having abrupt jumps from periods of low illumination to bright illumination when visual acuity may be lost and/or discomfort may be experienced. These levels of maladaptation may be correlated with subjectively determined levels of perceived luminance discomfort. Based upon the levels of perceived luminance discomfort that can be derived from the levels of maladaptation, the media content may be adjusted.
