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.
What else can I help you with?
Which layer has dark pigment to absorb extra light and keep the inside of the eye dark?
The layer in the eye that contains dark pigment to absorb extra light and keep the inside of the eye dark is the choroid layer. The melanin pigment in this layer helps prevent light from scattering inside the eye, allowing for better vision and reducing glare.
Nutritive or Vascular layer of the eye?
The vascular layer of the eye is also known as the uvea. It provides nourishment to the eye and consists of the iris, ciliary body, and choroid. This layer contains blood vessels that supply oxygen and nutrients to the structures of the eye.
The dark middle layer of the eye that prevents the scattering of light is the?
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)
What is the function of the conjunctiva?
The conjunctiva is a clear, thin membrane that covers the white part of the eye and lines the inside of the eyelids. Its main function is to protect the eye by producing mucus and tears, which help to lubricate the eye and keep it moist.
Neurons in the retina exit the eye forming the?
A+ students: the answer is optic nerve.
The layer of photoreceptors and neurons at the back of the eye is called the?
retina

What are neurons called that detect stimuli in the skin and eye?
sensory neurons
Layer of nerve tissue made up of sensory neurons that respond to light?
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.
Neurons in the retina exit the eye forming the what?
Neurons in the retina exit the eye forming the optic nerve.
Is the human eye has a double convex or a plano convex lens?
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
Where is conjunctivitis found?
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.
Why are everyones pupil black?
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.
What is the outer layer of the eyeball?
The outer layer of the eyeball is called the sclera. It is a tough, white, fibrous tissue that helps to maintain the shape of the eye and protect the delicate structures inside.
What is the pigmented layer of the eye called?
The pigmented layer of the eye is called the uvea.
What is the name of the outermost fibrous tunic of the eye?
The white portion of the eye is called the sclera.
