Toy eye

A toy eye comprising:

• a casing having a transparent top portion;
• a lens defining a through hole;
• a pupil received in the through hole of the lens, wherein the lens and the pupil are both made of soft resilient material, and clung to the transparent top portion of the casing;
• a push-pull element for pushing the pupil towards the transparent top portion of the casing or pulling the pupil reversely;
• 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 inten sity 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, wherein:
• when the driving element drives the push-pull element to push the pupil toward the top portion of the casing, a contact area between the pupil and the top portion increase, and a contact area between the lens and the top portion decreases as the lens being pressed by the pupil, thereby simulating a dilated pupil;
• and
• when the driving element drives the push-pull element to pull the pupil away from the top portion of the casing, the contact area between the lens and the top portion increases, and the contact area between the pupil and the top portion decrease as the pupil being squeezed by the lens, thereby simulating a contracted pupil.
