Why is it so hard for humans to move their eyes in different directions? (Like chameleons)
In: Biology
Chameleons have their eyes on either side of their head. There is little to no overlap in the area each eye is able to see. They are independent in that regard.
Us humans on the other hand, have both our eyes on the front of our face, and the area we are able to see with one eye is almost the same as the area we are able to see with the other one. So our brain is hardwired to move the two eyes together so the two images line up correctly and combine the two images into a single one. There is little to gain in having the eyes be able to move independently since they’re mostly seeing the same thing anyways, but being able to have both eyes effortlessly move together to combine images and see in 3D and past obstacles like branches is pretty cool.
