Similarly, one should avoid mobile phone screens for a long time, particularly in dim light or dark. After working for an hour or so with such equipment, a person should take a break and move out in open space for about 15-20 minutes. Here, one should fix the gaze on some far object. Children should be encouraged to be more in open spaces in their leisure time.
