- type of specialized light-sensitive cell in the retina of the eye that provides color vision and sharp central vision
- central neurons of the retina which carry light-elicited signals from photoreceptors and horizontal cells
- receives visual information from photoreceptors via two intermediate neuron types: bipolar cells and retina amacrine cells.
- side vision; what is seen on the side by the eye when looking straight ahead
- when our eyes focus straight ahead, allowing us to drive, read, and see details sharply
- outer covering of gray matter over the hemispheres

- where the light is absorbed and and transformed into the electrochemical signals used by the nervous system.
- If one object partially blocks our view of another, we perceive it as closer.
- Behind pupil, bends light rays to focus on retina
- Photoreceptors, ganglion cells, bipolar cells. and interneuron cells
- Cones containing only 2 of the 3 photopigments
- Objects close to you are in focus, objects far away are out of focus
