Keep in mind that the main thing is not to look at your smartphone for a long period of time at low or low brightness. It is best to view the content on your smartphone with the ambient light on both day and night because of the higher the brightness of the display, the load on your eyes decreases.
It is also important to turn off the devices an hour, and ideally a few hours before bedtime because this reduces the impact on the eyes of blue light, which interferes with adequate sleep. Modern smartphone displays often have protection modes and blue light filters, but they do not significantly change the situation, so it is better to abandon the devices at bedtime.
