A toy eye includes a casing having a transparent top portion, a lens defining a through hole, and a pupil received in through hole of the lens. The lens and the pupil are both made of soft resilient material, and clung to the transparent top portion of the casing. The toy eye also includes a push-pull element for pushing the pupil towards the transparent top portion of the casing or pulling the pupil reversely. The toy eye further includes a light processing element for sensing the change of the outside light intensity and generating a driving signal when the value of the change of the light intensity reaches or exceeds a predetermined value, and a driving element for driving the push-pull element to push or pull the pupil, upon receiving the driving signal from the light processing element.
