Claim 7:
8. A method of reducing a determined light spectrum on an electronic device comprising steps of:
determining, by detection or a user input, at least one factor comprising:
time a user is exposed to a display during a 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,

obtaining, for each of the determined factors, a predetermined maximum percent of reduction and a predetermined minimum percent of reduction for a light emission of the display within a light spectrum between 380 and 500 nm, wherein the predetermined maximum percent of reduction and the predetermined minimum percent of reduction corresponding to each of the determined factors are predetermined values, and
reducing, 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 a sum of each determined maximum percent of reduction and the sum of each determined minimum percent of reduction without completely blocking the light emission of the display within the light spectrum between 380 nm and 500 nm, and
detecting a background of an electronic document viewed by the user of the electronic device and switching 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.
