A kind of structure of simulation toy eye comprising the transparent crystal shell (31) the embedded member (32) and installation pin (33), of which the embedded member (32) is installed on the rear of the installation pin (33), with connection of the transparent crystal shell (31) with its section being sector. Comparing with the existing technology, the present invention extrudes and keeps distance with bottom. So, when magnified on arc optical surface of the transparent crystal shell (31), the present invention shows different appearances at various perspectives. That's pretty living. Especially, whatever perspectives you choose, you will feel the eyes are looking at you. With more realistic simulation, the idols are more living and attractive. In addition, the process art is very simple and suitable for assembly line manufacturing.
