You can add third arms and third eyes in stories (en.wikipedia.org/wiki/Will_the_Real_Martian_Please_Stand_Up%3F), but without some serious un-humanoid changeds, there's structurally no where for them to attach. | |

A very few extant animals, such as the tuatara (*Hatteria punctata) of New Zealand, still preserve the third eye in a sort-of functional form. | |

| Aug 12, 2018 at 11:02 | comment | added | Raditz_35 | Do you want them to be regular 2-eyed humanoids that then develop such an eye over a short period of time or do you want this to be something that developed a long way back in the evolution? | |
| Aug 12, 2018 at 6:38 | comment | added | StephenG - Help Ukraine | Note that your eyes are recessed in a protective "cocoon" of bone to provide some additional protection. A third eye in the forehead would require similar protection but being recessed would limit it's field of view. I'm hence skeptical that a third eye in the forehead would be an advantage and think it would be a significant disadvantage. Two additional eyes at the back would be arguably more useful than additional forward vision. | |
