  • Patent number: 6075525
    Abstract: The present invention is related to a method for preventing the eye injury when a user is operating a device, such as a computer, with a display. When a user operates a computer, the operating time will be accumulated. When the accumulating time reaches the preset value of a first interval (T1), an icon will show on the monitor screen for prompting the operator to blink eyes to moisten the eyeballs. When the accumulating time reaches a second interval (T2), a menu will show on the display screen. If the user chooses to execute the menu, the menu will generate various moving pattern(s) to direct the user's eyes moving upwards, downwards, leftwards and rightwards, and zooming in and out gradually. The illumination or size of said moving pattern(s) can be changed simultaneously.
