Triple Threat Iguanas have a so-called "third eye" on the top of their heads.
Known as the parietal eye, it looks like a pale scale and can't discern shapes or color-but does sense light and movement, helping iguanas anticipate predatory birds from above. Thanks to their regular eyes, iguanas also have outstanding vision and can see color and movement at large distances. What does iguanas vision look like?

The third eye is not a fully developed visual organ and cannot form images, but it can detect changes in light and dark and help the iguana. The pineal gland is responsible for regulating the iguana's circadian rhythms, or internal clock.
This means that the third eye helps the iguana "read" the time of day by sensing shadows and light changes. The Role in Survival The parietal eye plays a crucial role in the survival of green iguanas. Several species of lizards, including the iguanas, have a pale scale towards the back of their heads marking the parietal eye.
