EYE

Everyone can see from there eye but don't you wonder what an eye looks like or how it works. Don’t people wonder why the eye is some people are farsighted and nearsighted. Other people want to know what an eye looks from inside,how far can the eye see and, Why does your eye adjust to light.

   My group and I choses this topic because we want to know why the eye is the way it is. We got a couple of thing together to show you guy and to give you information about the eye.

 Why is it we can see colors and dogs can't? Unlike humans who have three different color sensitive cone cells in their retina red, green and blue dogs have only two which are  yellow and blue. This does not mean that dogs can't see green or red objects! It only means that they can't see green, yellow or red objects based on their color.

 Everyone can see from their eye but don't you wonder what an eye looks like or how it works. The human eye is an amazing organ it can see up to  3.1 miles away. But the way it works isn’t as simple. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina. The retina receives the image that the cornea focuses through the eye’s internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain. But there's animal can see way farther a human’s eye. Like a human they have no match for a eagles eye.

Why are people nearsighted and far farsighted? People are nearsighted because their eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Images focus in front of the retina, the light-sensitive part of the eye, rather than directly on the retina, causing blurred vision.  What is Farsightedness? Frasightedness develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. Why are people farsighted This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

The eye circulates the eyes in a form thats weird for example If you stress out too much you will have a blood clot inside your eye so your blood veins will start not absorbing blood so it will make like a little ball inside your eye and your will start getting blurry vision.Then that can lead to not seeing at all they have to do a surgery where it's a little laser that makes a little hole so your blood can get to your eye and hopefully you will start seeing.

We learned that the eye has many parts that can affect your eyesight. We learned that farsighted is that you  cant see near, and if your near sighted you cant see far.  We also learned how the eye works and has alot of characters.
