Claim 0:
1. An electronic device comprising:
a display;
a memory; and
a processor coupled to the memory and configured to:
determine, by detection or a user input, at least one factor comprising:
time a user is exposed to the display during use of the electronic device, ambient lighting of a place where the user interacts with the display, the time of day the display is operating, a working distance between the user and the display,

obtain, for each of the determined factors, a maximum percent of reduction and a minimum percent of reduction for a light emission of the display within a light spectrum between 380 and 500 nm, wherein the maximum percent of reduction and the minimum percent of reduction corresponding to each of the determined factors are predetermined values, and
reduce, based upon the obtained values, an intensity of the light emission of the display within the light spectrum between 380 nm and 500 nm, wherein the percent reduction is between the obtained maximum percent of reduction and the obtained minimum percent of reduction without completely blocking the light emission of the display within the light spectrum between 380 nm and 500 nm,
wherein the reduction of the intensity of light emission of the display between the maximum and minimum percent of reduction only within the light spectrum between 380 nm and 500 nm is performed by reducing at least a percentage of the light spectrum emitted from the display,
and wherein the processor is further configured to detect a background of an electronic document viewed by the user of the electronic device and switch the background of the electronic document viewed by the user to a background with a reduced emission in the light spectrum between 380 and 500 nm.
