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!

Dear Dish-It In The Forums

Goodness... I see where your mother is coming from: if you eat too much, no matter how healthy the food is, and don't work off the calories, you're going to gain weight. But she's being very obsessive and dramatic about it. There is nothing wrong with eating pizza or a cookie every now and then, and there's nothing wrong with relaxing from time to time either. As long as you aren't constantly eating junk and not burning the calories, then you do not have a problem. Eating unhealthy things every now and then does not make you fat. EATING every now and then does not make you fat. Try explaining this to her, calmly and patiently. Tell her that you don't want to be forced to do all of this exercising - being forced to exercise makes it a lot less interesting. Do not take "This is for your own good" for an answer; if you do not want to do it, it is NOT for your good. (This, of course, would be a different story if you were actually fat.) ALSO tell her that exercising too much and not satiating your cravings is JUST AS UNHEALTHY AS BEING FAT IS. If you were to not eat healthful meals and not snack every now and then, no matter how healthy or unhealthy the food is, plus exercise so frequently, you would not be healthy.  Eating is good for you, even if the food isn't. Eating too little and eating too much is not healthy. Exercise is good for you. Not exercising enough and exercising too much is not good for you. If you talking to her doesn't help, try telling another adult how you feel, and maybe they can help get it through to her. Regardless of what happens, take care of yourself. Moderate how much you eat, but don't limit yourself to less than you feel you need. Exercise, but don't do something you don't want to; working out should be fun. Good luck with everything. I'm really sorry that she makes you feel so badly about this.

I'm perfectly happy with myself. I'm around 5'6" and somewhere between 140-150 pounds, and I don't feel fat. But my mom is constantly telling me that I am, or, at least, that I'm going to be. She forces me to go to exercise classes because I don't like many sports, tries making me go on diets, but I don't want to. She tells me that if I continue the way I am, having an extra cookie once in a while and only eating cereal for breakfast, that I'll end up fat, and she makes sure to emphasize how horrible that is for a person to live with. She rolls her eyes and sighs whenever she sees me getting a snack, and just in general makes me feel awful for eating the things I like and for relaxing. I've told her that I don't want to do these things and that she makes me feel bad when she says things like that, but she swears it's for my own good and that I should never want to be fat, that it ruins people's lives. How should I deal with this?

I know I need to tell her as I don t like keeping secrets from her. I know this was a bit ago, but I truly hope that you were able to be open with your mother. If you feel as if they won't get mad at you, then chances are that your guardian will not. Honesty is the best policy, and if you feel guilt keeping a secret, then it is one you probably shouldn't be keeping.

I agree with @rainbowpoptart. You really shouldn't worry about relationships that much given your age. I promise, they're better things to worry about than boys and more secure romances occur later on in life anyways. But, given the situation, you shouldn't worry about either. The boy is unfaithful and so is your friend. If your best friend really valued your friendship, she would not have put it in a position that could end it. Don't waste your time on those who will not put you first just as you do for them; better people will come into your life and they are the ones who you should really worry about.
