Abstract
Abstract An anti-eye strain apparatus and method which automatically adjusts the brightness of a display to cause the muscles of the eyes of the user to adjust and refocus such that eye fatigue or tiredness is reduced or eliminated. The brightness is varied within a particular range and the brightness within this range is occasionally or periodically adjusted. The changing brightness preferably follows a predetermined pattern or cycle. These brightness changes may be perceptible or imperceptible to the viewer. The brightness of the display may be adjusted electronically or mechanically, for example by a potentiometer, by a computer attached to a monitor, for example by an application or software, or by changing the palette of colors or the gray scale.
