WebApr 18, 2013 · The question under study here is how myopia development is related to the flicker frequencies and one possible hypothesis is that myopia increases with flicker frequency. As an artificial light, FL has a variety of frequencies. Is myopia more susceptible to a certain frequency, or the higher the frequency, the more myopic in refraction? WebSimilar effects can occur if light flicker with a frequency of up to 2000 Hz 11. But, again, it depends directly on the flickering intensity. The screen flickering will not cause any biological reactions at a certain level. And this level is easy to calculate 11: No harm: Flicker Frequency * 0.0333; Low-risk: Flicker Frequency * 0.08
