The present relates to an eye position display housed in an iris recognition system and a method thereof. Particularly, the iris recognition system comprises: a board (PCB) including a controller for controlling emission of light; a light emitter with a LED mounted on the PCB for emitting a light and uniformly scattering and equalizing the intensity of the emitted light; a lens unit for maintaining a focal length of the emitted light from the light emitter, refracting and converging the light at a constant angle, and passing the light through a predetermined portion only so as to display a position where a user's eye is should be; and a reflector unit for reflecting every wavelength band that passed through the lens unit except for a wavelength of a predetermined light.
