How do our eyes work?

 For writing I did it about how our eyes work.

Purpose:explain

R.T:Conjunctions and connectives

We all watch tv and do online work but how do our eyes make us see the world around us and how does it work?. We first go in the eye and you will see four parts of the eyes called. The Cornea, that is the front of your eye, the Iris the red part of your eye, the Lens, Vitreous and the Retina. You might think that's done but I haven’t explained how these parts work.

For example if I had a candle and you were looking at it the light first will go to your Cornea then it gets bent to the Lens. After going through the Lens it bends a second time after it arrives at the Retina. It is like a  reversed image and turned it upside down like if it was the end of a story, but the world would always appear upside down. In the brain the image is right side up but before it goes to the brain it needs to go through the Impulses along the optic nerve before it goes through the brain. Once it is done in the optic nerve it then goes to the occipital lobe in your brain when the image is there it forms it gets its proper perspective.

Now let's talk about the eyes shape with normal vision the focuses on the retina at a location called the Focal point but if the eye is nearsighted the eye is bigger and that means Focal point is a not on the retina but glasses with concave Lens the Focal point is at the right location. But with farsighted vision the eyes length is to short when that happens the focal point is behind the retina. That's all about the eye and it is sure a lot of explaining just about the eye. 

I enjoyed learning about the eye and how it works.

What do you know about the eye?

Our human body

 This week for topic it was about the human body. I got to do my fingerprint and learn some things about diabetes.


I enjoyed learning about diabetes and seeing my fingerprint.
What is your favorite thing about the body?
