Bu very few people realize that they are subjecting the body day after day equivalent to an effort of lifting and carrying heavy things all day.

Displays often come with their refresh rates set too low 60 Hz or 60 screen-refreshes per second—- which makes the screen flicker. Turning up the rate to about 72 to 85 Hz will reduce flicker and in turn reduces eye strain.
