I do not make these heads myself they are 1/6th sculpts from a company called Dragon Toys these are very detailed collector figures ,each character has it's own unique head sculpt unlike the cheap Action Man figures. Click this link PICTURETRAIL to see some of the many heads I own and have added more detail to. These heads are static and require manipulation using PhotoShop to add blinking and mouth movements, I am slowly getting better at this here is a link for a TUTORIAL I did on blinking using the PhotoShop morph tool.
Here is a still from the test below of a "Dragon" head with real eyes and a blink added in post.

Eyes open.
Blink frame.

Zoom close up end shot.

Original image, the eyes are still good.
