An eyeball tracking method is provided. A left infrared light source and a right infrared light source are alternately turned on. A left tracking camera and a right tracking camera are controlled to correspondingly shoot the turned-on left infrared light source or the turned-on right infrared light source to form turned-on odd-frame tracking images and turned-on even-frame tracking images. Turned-off even-frame tracking images and turned-off odd-frame tracking images when the left infrared light source and the right infrared light source are alternately turned off in sequence are obtained according to the turned-on odd-frame tracking images and the turned-on even-frame tracking images. The turned-on odd-frame tracking images and the turned-off even-frame tracking images are combined to form a tracking image of one eye, and the turned-on even-frame tracking images and the turned-off odd-frame tracking images are combined to form a tracking image of the other eye.
