A digital screen does not radiate harmful energy against human eyes, but staring at the screen for a long time without pauses does increase eye strain. There is no evidence to support the claim that exposure to digital screens contributes to the risk of macular degeneration. [31] [16] [32]
For example, after staring at a computer screen and looking away, a vague afterimage of the screen remains in the visual field. A stimulus consistently produces the same afterimage, which is dependent on the stimulus intensity and contrast, the time of fixation, and the retinal adaptation state.
However, looking exclusively at the effect social media usage has on girls, there was a strong association between using social media and poor mental health. [47] [48] The evidence, although of mainly low to moderate quality, shows a correlation between heavy screen time and a variety of health physical and mental health problems. [7]
