Light flickering can be detrimental to humans even if imperceptible. Headaches, migraine, and/or eye strain can result from exposure to flickering light. This disclosure describes techniques to detect and monitor light flicker. An ambient light sensor detects flickering in environmental lighting. Environmental light intensity is measured over a wide spectrum covering the human perceptive range. The peak flicker frequencies (and their magnitudes), flicker percentages, etc. are determined. If a substantial amount of flicker (greater than a threshold) is detected, an alert is provided. Furthermore, auto-generated instructions enable users to determine the light source that is the source of flickering.
