What else can I help you with?
Which cells comprise the chain of five cells in the visual pathway beginning with the photoreceptor cell of the retina?
The chain of cells in the visual pathway from photoreceptor cell of the retina includes bipolar cells, ganglion cells, optic nerve fibers, and lateral geniculate nucleus cells in the thalamus. These cells work together to transmit visual information from the retina to the visual cortex in the brain.
How do the structures of the eye work together to help us see?
The cornea and lens focus light onto the retina at the back of the eye. The retina contains photoreceptor cells called rods and cones that convert light into electrical signals. These signals are sent through the optic nerve to the brain, where they are processed and interpreted as images.
Can your eyes work independently of each other?
No, human eyes are connected to the brain through the optic nerve, which allows them to work together to create a single visual perception. While each eye can move independently, they still send signals to the brain to merge the images into a cohesive whole.
What are the two transparent structures of the eye?
The cornea and the lens are the two transparent structures of the eye that work together to focus light onto the retina at the back of the eye. They help to refract or bend light rays so that they can be properly processed by the retina for vision.
What forms the relative sharpness of image in the eyes?
The relative sharpness of an image in the eyes is determined by the ability of the eyes to focus light onto the retina. This process is primarily controlled by the cornea and the lens, which work together to adjust the focal point of incoming light to form a clear image on the retina. In addition, the sensitivity and resolution of the retina also play a role in the perception of sharpness.
How does the optic nerve work?
The optic nerve is a group of nerve fibers that function to provide vision. The optical never works by transferring electrical impulses to the brain from a part of the eyes known as the retina.

What body part is the eye connected to?
By the optic nerve, which is connected to the brain. The optic nerves takes nerve signals from the retina and sends it to the brain.

How does the retina work?
"The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve." http://en.wikipedia.org/wiki/Retina
How does the process of seeing work?
When you look at something, light enters your eye and hits the retina, where it is converted into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are processed and interpreted as visual information, allowing you to see and perceive the world around you.
What is the part of the eye that converts light energy to electricity into electrical signals?
First you must understand how light is transferred into an image by the eye. Located in the retina at the back of the eye are millions of photoreceptors. The way I understand them to work is they are constantly blocking any impules from themselves to the next connection, ganglions. When light hits these potoreceptors, the impulse is released, travels through the ganglion, and then is transmitted to the actual optic nerve. So according to this question, the photoreceptors are the trigger of light to impulse, but the answer to your question is the ganglion that transmitts the impulse to the optic nerve.
What eye functions do not work when you are blind?
either the light sensitive cells in the retina are not working or the optical nerve is damaged
What parts of the eye are involved with the inability to see. this is dealing with Blind spots?
The parts that are involved are the retina, brain cells called neurons, photo receptors, the optic nerves, and the iris. They function like a camera. How? Well the optic nerve head, neurons collected together passing as a whole through our photo receptors and it forms our optic nerve; they work as messengers to our brain. Once our eye sees light, the neurons transfers it to our brain as a picture. So when our blind spots kick in that means that there are no neurons passing to our photo receptors in that area, as in nothings being transmitted to our brain so there's no picture. Um... i hoped i was a good help to you XD
What are the parts of the eye?
There are different parts in eye;1.Sclerotic: Sclerotic is the outer coating of the eye which is white in colour.2.Cornea: The front part of sclerotic is transparent to light and is termed as cornea.3.Iris: Iris is just at the back of cornea.4.Eye Lens: Eye lens is a double convex lens.5.Ciliary Muscles: The eye lens is held by ciliary muscles.6.Pupil: At the centre of the iris there is a hole through which light falls on the lens.7.Aqueous humour : The space between cornea and eye lens is filled with a transparent fluid called aqueous humour.8.Vitreous Humour:A jelly like transparent fluid which is filled between between eye lens and retina.9.Retina : Retina serves the purpose of a screen in the eye.10.Optic Nerve: Optic nerve carries the information to brain.11.Principal Axis:a line that passes through the center of curvature of a lens so that light is neither reflected nor refracted.12.Blind Spot : The region of eye containing the optic nerve is not at all sensitive to light and is called blind spot.13.Yellow Spot : The central part of retina.14. Eye Lids:protect the eye from dust and light.
Can your eyes work independently of each other?

How does the human eye work?
The eyes form an exception to the rule that the left side of the brain controls the right hand side organ and vise versa. Each eye is split such that the left half of our vision goes to the right side of the brain and vise versa. While fixing the gaze, each point in the view is mapped to the same place in the brain via BOTH eyes. This was first proposed by Isaac Newton, and confirmed 150 years after is death. The eye works by focusing light through the cornea and lens onto the retina. The retina converts light to nerve signals that travel to teh brain via the optic nerve. The brain interprets those signals and you understand what yuo are seeing.
