Anti-eye strain apparatus and method
First Claim
1. An automatic screen brightness controller for reducing eye strain, comprising:
- brightness control software stored in a machine readable storage media;
a processor operatively connected to said storage media; and
a display of the type that permits the brightness to be varied;
said brightness control software including instructions that direct the brightness of substantially the entire display to be varied over time within a range of brightness in accordance with a predetermined pattern, wherein the range is less than 80 percent of the total range of brightness of the display and the screen content may be easily seen throughout the range.

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 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.
