Choroid
Choroid is a thin, dark membrane due to ________
- keratin
- melanocytes
melanocytes
Covers about 5/6 of the interior of the eyeball

Choroid
Nourishes the outer part of the retina (RPE & photoreceptors)
- Choroid
- Iris
- Ciliary body
Choroid
Provides dark chamber (many pigmented cells), aids to darken the eye
- Choroid

- Ciliary body
Choroid
Prevent dispersion of light- attain clear image of an object
- Choroid

Choroid
for dim illumination/scotopic vision
- rods
- cones
- nerve fibers
rods
for day illumination/photopic vision, color perception
- rods
- cones
- nerve fibers
Cones
for transmission of visual and pupillary impulses
- rods
- cones
- nerve fibers
Nerve fibers
Thin, transparent membrane upon which the Images are cast and in where nerve are generated
- RETINA
- SCHEMATIC EYE
RETINA
Mathematical or physical model that represents the basic optical features of the real
- RETINA
- SCHEMATIC EYE
SCHEMATIC EYE
Same plan as a human eye for purpose of study/experiment
- RETINA
- SCHEMATIC EYE
SCHEMATIC EYE
Employs average value of radii distances, indices designated as optic constant
- RETINA
- SCHEMATIC EYE
SCHEMATIC EYE
Made a six surface eye model (crystalline lens with a high Index core and index shell)
- GULLSTRAND
- EMSLEY
GULLSTRAND
Later reduced to four surfaces since ray tracing is time consuming
- GULLSTRAND
- EMSLEY
GULLSTRAND
Made a single surface model for simplicity and speed of ray tracing
