Simply explained, the light sensitive cells inside the eye are located on the retina. There are two different types of photoreceptor cells: rods, which read light intensity or back and white; and cones which are color sensitive. Both rod and cone cells are then connected to ganglion cells. These cells then bundle into the optic nerve which carries the signals from the photoreceptor cells into the brain. Also, the photoreceptor cells are the furthest layer form the front of the eye and are closest to the back wall or choroid layer of the retina.
it is the retina.
/according to other answers on other sites\
The vascular layer of the eye is the middle layer. It is also called the uvea. The vascular contains the iris and lens. The iris contains the light levels inside the eye.
the pupil
choroid - a highly vascular membrane in the eye between the retina and the sclera; a dark pigmentation minimizes the scattering of light inside the eye.(http://www.thefreedictionary.com/choroid)
A+ students: the answer is optic nerve.
they are called cones :)

The vascular layer of the eye is the middle layer. It is also called the uvea. The vascular contains the iris and lens. The iris contains the light levels inside the eye.
sensory neurons
The retina is the layer of nerve tissue in the back of the eye that contains sensory neurons called photoreceptors. These photoreceptors, specifically rods and cones, respond to light and convert it into electrical signals, which are then transmitted to the brain via the optic nerve, allowing us to perceive visual information.
the pupil
Rods and cones are inside a layer of the eyeball called the retina.
Conjunctivitis is inflammation of the conjunctiva. The conjunctiva is a layer of epithelial cells that cover the sclera (in the eye) and the inside of eyelids.
The choroid layer in the eye has a black color pigment on it. Also, the light entering the eye is not reflected because light rays entering the pupil are absorbed by the tissues inside the eye.
The pigmented layer of the eye is called the uvea.
Yes, th ration of motor neurons to muscle fibers are greatest for the muscles that control eye.
