Also Known As: Pineal Eye — Third Eye
Introduction
The parietal eye is a small degenerate eye (containing a rudimentary lens and retina) situated on the dorsal midline between the normal eyes of some lizards, including the green iguana. It is commonly referred to as the 'pineal eye' or 'third eye'. It detects both UV light and heat, connecting with the pineal body.
Function
The parietal eye appears to be involved in hormone production and thermoregulation (by acting as a light dosimeter). It is photosensitive, detecting light and dark - which allowing lizards to detect the movement of predators.
