The Retina Part is a complex structure of the eye that is responsible for vision. It consists of three components: the Fovea (5 letters), ROD (3 letters) and CONE (4 letters). The Fovea is a small area in the center of the retina that is responsible for sharp central vision. The Rods are located around the Fovea and are responsible for peripheral vision and night vision. The Cones are also located around the Fovea and are responsible for color vision and detailed vision. Together, these three components of the Retina Part work together to provide us with our vision.
