Looking After Your Eyes

Do you know how your eyes work? Or why some kids have to wear glasses in order to read what the teacher is writing at the front of the classroom? Since Eye Exam Month falls in August, Kidzworld is reminding you to get your vision checked before you head back to school, as well as bringing you all the facts you need to know about your eyes.

How Your Eyes Work

The human eye is about the size of a ping pong ball, with a bulge at the front. It is mainly made up of the cornea, iris, pupil, lens, retina and optic nerve. Each part plays an important role in how an image is transferred to your brain. When you look at something, light reflects off of the object and enters your eye through the pupil (the black dot in the middle of the eye). The iris (the colored part around the pupil) controls how much light goes through the pupil. If it's dark, the iris' muscles will make the pupil dilate (get bigger) to let in more light. If it's bright, the pupil will constrict (get smaller) to let in less light. This light then enters the lens (similar to a camera lens), which focuses the picture onto the retina at the back of your eyeball. The retina changes the light into a message and sends it down the optic nerve to the brain.

When the World Is a Blur

Did you know that you're born farsighted with a vision of 20/400? That means you can only see the big "E" on an eye chart! By the age of two, your vision improves to 20/20 so that you're able to see the smallest letters on the bottom of the chart. But as you get older, your vision can go from clear to blurry - and it has nothing to do with those eye crusties you wake up with. It's usually due to genetics, so if your mom or dad has vision problems, chances are high that you will too. If you find yourself squinting to see things clearly or you're bringing your book a lot closer to your nose than you did before, then you probably need corrective eyewear, like glasses or contact lenses, to help you see properly.

Near, Far, Wherever You Are...

You're nearsighted if you can only read things that are close to you. But you're farsighted if words are cystal clear when they're far away. Wearing glasses or contacts can correct both of these vision problems. If you're having problems with your eyesight, make an appointment with an eye doctor (ophthalmologist or optometrist) to get a vision test. You should see your eye doctor at least once a year to maintain good eyesight.

Did You Know?

  • One in four kids aged five to 12 have vision problems in the US.
  • Having 20/20 vision means you can see an object clearly from 20 feet away.
  • Carrots, milk and cheese are good for your eyes because they're full of vitamin A, which helps you see at night.
  • August is Eye Exam Month, so be sure to get your eyes checked out before heading back to the classroom!

I'm not quiet sure what's a real friend and what's a fake one anymore. I know when there's a friend who's only a school friend rather than an 'outside' friend as well, but at the same time it makes me so confused. Here's my story: There's a girl named Xian. We had a unique way of becoming friends ... but it clicked. For the whole year I've been trying to keep in contact with her ... but she's not very willing to try and put in any effort to stay in contact with me. Her personality is beyond sweet, and her skills at art are even better. If she was to have an award, it would be a giant trophy with her face plastered on it and big bold letters listing 'Nicest Girl In The World!' ... Its just ... she lied to me.  I was all about this friendship. I was ... i'll admit ... sort of a lost puppy following around her owner.  So, I got her this T-Shirt she really wanted for her birthday, and not long her birthday was mine, April First. I was expecting at least a letter, or maybe even something cheap. It didn't really matter to me.  But on my birthday she didn't even come to school. Nor when she got back did she ever say sorry, or give me any be-lated gift of any sort.  That should have been my first clue. Even my mother started catching on. My second clue was she even told me she was oblivious and wasn't good at keeping in contact. I thought she was joking. How could a friendship so sweet be tossed out just like that? My third one was near the end of school, one of her friends in elementary was bragging about the plushies she got from Xian. Apparently she had four from her.  Xian had originally told me it was AGAINST her religion to give out gifts to other people. I knew she wasn't lying about her religion in general, because I met her mom on a field trip and she was quiet ... different. But I didn't understand why Xian had gotten so many small plushies for her, and yet not a single small stamp for me? My last clue was the last day of school. She didn't even try to say good-bye or even hang out with me for that matter. I know what you're thinking. "Girl, you've gotta be kidding me if you can't see that she has no intention of being your friend!" But this girl was the nicest to me. She stood next to me during harsh times, and comforted me when I was down. She told me I was important.  And you don't get many friends to do those special things to you. It was rare to have a friend make me feel so tall and worthy.  ... So ... I can't understand ... why'd she do all that .... and suddenly ... just ... walk away ...
