The retina contains the light receptors. Rods for light level, and cones for colour.
You can perform a simple experiment to show that the colour receptors are only in the centre of the eye.
First of all get a box of coloured crayons and without looking at them, pick one, and hold it behind your head. Make sure you don't see it yet!
Looking fixedly ahead, gradually bring the crayon round the side of your head. Notice where your hand is when you first see the motion of the crayon. Continue bring it forward, noting when you can first determine the colour of the crayon.
Try again for randomly selected colours.
The retina
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.
The sensory anatomy of the eye contains three layers of nervous tissue. Light passes through the two superficial layers, all the way to the deepest layer. From there, the information is processed in the opposite direction, through the middle layer and then to the most superficial layer, where it is collected and then sent to the brain. If the eye were not "inverted", light would strike the most superficial layer and then be processed through the middle layer to the deep layer and then to the brain.
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 sensory of the membrane eye has the letters r,e,n,a,t, and i.
sensory neurons
The layer of the skin that contains sensory receptors is the epidermis. There have been reports of the dermis also containing sensory receptors.
Sensory organ
Sensory system
The pigmented layer of the eye is called the uvea.
dermis
The reflective layer in the lining of the eye is called the tapetum lucidum.
