“What we see, and how we see it.”
What is the eye? Because to us as humans the eye is something we use to see our way through society. We use the eye to observe what we like and dislike, and we use the eye as a means of physical attraction. But what is it about the eye that makes it the most unique, is that it’s used as a visual means of storing information. Whatever we see through our eyes, is then sent to the brain And when we see this item again, the brain sends a signal to the eye to aid you in remembering what it is you’re seeing. The eye is a very important callback go between from your brain to the world around you via your eyes.
This is the outer most layer of the that covers the eye. There are no blood vessels that are in in place to provide nourishment for the cornea. Instead, the tears give it nourishment and the aqueous humor behind the cornea. Light refracts off the eye, as long as the cornea is transparent. There are five basic layers to the cornea:
This is the portion of the eye that is a dark center min the middle of the eye. This area acts just like the aperture of a camera would open and close, allowing for light to enter. The pupil is smaller in bright light and bigger in low light, and this is attributed to the pupillary reflex.
This is the portion of the eye that lies between the cornea and the lens. There are two pieces of smooth muscle that the iris is comprised of: the dilation and contraction. The muscle determines how much light reaches the retina through sensory tissue.
This is the portion of the eye that is behind the iris which aids in the clear imaging of what the eye sees from bent light rays. The lens receives its nutrients from surrounding fluids, mainly the aqueous humour. Waste products are also removed through these same fluids.
The light sensitive part of the eye, and the inner most portion of the eye that forms visual images from the triggered impulses that pass through the optical nerve. This is also the portion of the eye that is key to clear vision. Given that it is key to good vision, you must maintain your health because there are quite a few illnesses that can lead to damage of the retina:
The cranial nerves that serves as a transmitter to the brain from the back of the eye. These nerves aid in interpreting images from the brain to the eyes.
And with knowing how the eye works and all its part, the way we base our feelings come through the eye. We experience so much around us that we need to make sense of. So what do we do, we take what our eyes see, and from previous experience we judge accordingly. This way of life is not only social, but it has aided in human survival on this planet forever.
