Internal features of the Falcons Eye

Accommodation: Flacons use their memory and visual information to get the size and distance of their prey. They first remember how large the prey is and then judge whether it's near or far. Accommodation is when small ciliary muscles that surround the eye make a curve so that the eye can focus on near

and far objects. When a prey moves closer or farther from a falcon, the falcon's eyes remain focused but the curves on the lens change rapidly.

Binocularly: Something that humans and birds both have in common is that we both have eyes that face forward. A binocular vision is when the the field vision of the right eye and left eye overlap. A human eye overlaps 120 degrees while a falcons eye overlaps 90 degrees which helps them get a sharp and 3D image.

Second Fovea. Humans only have a central fovea while falcons have a central and lateral fovea. A fovea is a part of your eye where the vision is the sharpest. Having two foveas helps make a sharper image because then you have two parts where your vision is the sharpest.

Pecten: The pecten is a thin tissue that extends from the retina to the lens. Falcons have one of the largest pecten of all birds. The pecten provides nutrients for the vitreous humor. That reduces the amount of blood vessels in the retina. The fewer blood vessels scatters the light coming into the eye. Raptor vision has become one of the sharpest vision between all organisms.
