There is no clear causal relationship between playing cell phones with the lights off and the development of macular degeneration, but playing cell phones with the lights off frequently can increase the risk of macular degeneration.
Playing cell phones with the lights off is bad for the eyes because in a dark environment, the light from the electronic screen of the cell phone is relatively harsh, and prolonged close eye use can easily lead to spasm of the ciliary muscle or excessive evaporation of tears, and the patient can experience increased myopia, visual fatigue, dry eye and other uncomfortable symptoms. Prolonged light stimulation can also increase the risk of macular degeneration.
There is no clear causal relationship between playing cell phones with the lights off and the development of macular degeneration, but chronic light damage can lead to macular degeneration, so patients need to develop good eye habits to avoid damage to their vision.
It is recommended that patients who experience eye discomfort from playing cell phones at night should consult a doctor promptly to assess their condition and follow the doctor’s instructions for treatment.
