The invention relates to a toy eye which comprises a front cover, a rear cover, an electromagnet and an iris and pupil assembly, wherein the front cover is provided with a first through hole and a first lateral wall, the rear cover is matched and connected with the front cover to form an accommodation space, the electromagnet is fixedly arranged on the rear cover, and the iris and pupil assembly is positioned in the accommodation space; the iris and pupil assembly comprises an elastic iris, an elastic pupil embedded in the iris, a metal body which is fixedly arranged on the pupil and close toone side of the electromagnet and a bearing part; a second through hole which corresponds to the metal body is arranged on the bearing part; the iris and the pupil are connected to the bearing part and the metal body passes through the second through hole and corresponds to the electromagnet; and the iris and pupil assembly is fixed at the inner side of the first lateral wall and matched with thefirst through hole. The toy eye ensures that the elastic iris and the elastic pupil stretch under the stressing state by utilizing the electromagnet to attract the metal body connected with the pupil,thereby changing the size of the iris and being simple in structure.
