1. A method for virtual reality-based visual field inspection in which a processor of a head-mounted display performs a visual field inspection, the method comprising:
outputting a background including a background image and a focus point image;
outputting an indicator in the background;
sensing user input from an examinee according to output of the indicator,
wherein the outputting of an indicator in the background includes determining a position where the indicator will be output in the background, outputting the indicator with predetermined brightness at the determined position, and continuously increasing the brightness of the output indicator,
measuring a reaction speed of the examinee,
wherein the measuring of the reaction speed of the examinee includes calculating the reaction speed by outputting an indicator for measuring the reaction speed with predetermined brightness at a predetermined position in the background, and then sensing user input; and
acquiring a visual field inspection result on the basis of the reaction speed, an output position of the indicator, a point in time of outputting the indicator, and a point in time of the user input.
