The Eyes Of The Eyes

As vital organ of vision, the eye, allows us to learn more about the world around us more than any other organ or senses. Sight, the physical sensory experience and vision, the metaphysical concept of how our brain interprets images both work harmoniously and play a huge role in our everyday lives. However, almost a billion people are either blind or visually impaired simply due to not having a pair of glasses. Being able to lead people in the direction of good vision is what developed my interests.

Explain the visual process, including the stimulus input, the structure of the eye, and the transduction of light energy.

After being shown a picture of an elephant they eye will take the light that is reflected from the object and it will enter the eye through the pupil. Then the light will be focused by the cornea and the lens to form a sharp image of the elephant in the retina. The retina is the network of neurons that cover the back of the eye and contains the visual receptors for a person vision. The visual receptors are made up of cones and rods that contain light sensitive chemicals called visual pigments. Visual pigments reacht to light and cause a triggered electrical signals to occur. These electrical signals will then flow through a network of neurons and this network of neurons is what makes up a persons retina. After the flow through the network of neurons occurs the electrical signals will emerge from the back of the eye in the area

Focusing an image clearly onto the retina is the initial step in the process of vision, but although a sharp image on the retina is essential for clear vision, a person does not see the picture on the retina. Vision occurs not in the retina, but in the brain. Before the brain can create vision, the light on the retina must activate the visual receptors in the retina by a two-element

When it comes to vision, we see things based on the light reflected from surfaces. The reflected light waves enter the eye through the cornea at the front of the eye, it's resized at the pupil, focused by the lens, and hits the retina at the back. The light is then detected by rods and cones, photoreceptors, which alters the light into electrical signals. The optic nerve transmits those vision signals to the lateral geniculate nucleus, where visual information is transmitted to the visual cortex of the brain then converts into the objects that we see.

The retina is what houses the eye’s rods and cones. The eye has about 6 million cones and 120 million rods. Both rods and cones get their names from their shape. Rods do not provide color vision, and are sensitive to dim light. Cones function well in the day and provide color vision.

The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light.

The brain identifies what it sees in a series of steps. The brain makes a feature map of the eye breaking the visual field into sections. Information collected in a particular section of the visual field will always be sent to the

In the center of the iris is the pupil. Iris function is to control the size of the pupil. This pupil dilation allows a certain amount of light to enter the eye. A bright environment stimulates limiting diaphragm to contract the sphincter muscle and reducing the amount of light entering the eye. A dark room stimulates the dilator to relax and dilate in the effort to increase the amount of light entering the eye. The pupil constriction also occurs when the lens changes focus so that the eye can see something on a fence. This is known as the, Äúnear reflection., AU Sometimes the student does not respond properly due to problems in nerve or cranial

Fluid circulating inside the front portion of the eye is produced by a structure called the ciliary body, which is located behind the iris. This fluid moves through the opening of the pupil, passes into the space between the iris and the cornea, and drains out of the eye through a tissue called the angle. With glaucoma, the passing of fluid

The eye is an opaque eyeball filled with liquid. In the front of the eyeball is a transparent opening known as the cornea. The cornea is a thin membrane

The eyes have always been known as the windows to the soul. Perhaps this is because the eyes tend to convey people's most basic emotions. Either way, the eye’s can tell someone a lot about a person. Someone with green eyes may be perceived as mysterious and alluring. They can capture your heart. Blue eyes may cause a chill, from the sheer coldness of a glance. While a pair of earthy brown eyes may bring warmth and comfort to any room. Whether green, blue, or brown everyone’s personality can be directly related to eye color.
