A simulated eye capable of being changed between a contracted state and a dilated state. The simulated eye includes a semispherical eyeball having a transparent portion, a inductive coil, and an elastic film. The inductive coil coils around the elastic film, a size of the coil elastic film is changeable when being operationally supplied with electricity. When the inductive coil drives the elastic film, a size of the elastic film is changeable, whereby the simulated eye is changed between the contracted state and the dilated state.
