Abstract
An eye-movement tracking apparatus and an electronic device are provided. The eye-movement tracking apparatus includes a light source, a lens group, a hot mirror, and a compact camera module. The light source is configured to emit a light ray to an eyeball of a user. The light ray is reflected by the eyeball to form a first light ray and a second light ray that are emitted to the lens group. The first light ray is reflected by the hot mirror for N times to form a third light ray. The second light ray is reflected by the hot mirror for M times to form a fourth light ray. Both M and N are natural numbers, and M and N are different. The optical component allow the third light ray to enter the image sensor, and prevent the fourth light ray from entering the image sensor.
