Light oscillates, normally at very high frequencies not noticeable by the human eye. Therefore our instantaneous perception is a continuous ray of light. Just like TV or computer screens having their own defined oscillating refresh rate, otherwise known as frame rate. Nowadays with our power grid running at 50Hz or 60Hz, artificial light is prone to oscillate at 100Hz or 120Hz. Since this oscillation frequency is low, it’s easier for the human eye to perceive a stroboscopic effect that may cause discomfort and health concerns to some.
Light flicker percentage is the measurement of peak-to-peak contrast of light output. If it exceeds certain threshold at lower frequency, our eyes will be strained to perceive light as continuous.
ComfyEYE technologies smoothen the light flicker percentage to less than 5%.
