The World in Your Eyes

Internet Contacts 1: Can you have contacts with Wi-Fi?

        Have you ever saw your friend in a classroom that was completely were zoned out, and then the teacher (seeing how helpless he was) calls him to tell you the answer to a problem, and he just stares and think "Boy, I wish I had my phone with that calculator I never used". And have you ever thought that it would have been really helpful if there was a way for him to find information without having to sneak his phone to school? Well now, recent developments in engineering have shown that it is possible to have the internet EVERYWERE. Scientists and engineers have worked together to make a primitive way of using contact lenses to carry the internet wherever you go. In other words, that friend of yours would be really happy.

    So how does this marvelous system work? Well, there is a circular antenna around the perimeter of the lens, which has a circuit that is holding up a LED at the center of the lens. The antenna is used to communicate with the computer that the scientists control so that they can monitor and change the color of the lens and what it does. The people that made this lens have already tested it on animals safely, namely rabbits. They are now planning to make a multi-pixel display so that you can organize your inbox, use the google calculator, and one of the most important uses, see Facebook profiles of strangers (you want to know who your saying hi to!). You can even wear eyeglasses with the LED display if you don't like contacts (like me). However, there could be a couple problems.

    For one, a light that close to your eyes can severely damage them, unless the light is extremely dim, which can make it hard to read. Also, the minimum eye focus distance poses a problem. What's minimum eye focus distance? Okay try this experiment:

   -Ingredients needed:
                 -Hand
                 -Eyes
                 -Instruction manual (this post)

• First, put your hand about a foot away from your face.
• Then, slowly bring it closer.
• Stop. Then check if your cross-eyed, or if the hand starts to look blurry. No? Move on.
• Repeat until your cross-eyed, or if your hand is starting to look fuzzy.

When your feeling cross-eyed, then that is the minimum focal distance of your eyes. Now do you know what minimum focal distance means? It means how close an object can be to your eyes without appearing fuzzy. So if your wearing these contacts, then it would be really hard to read stuff on it. So how can we fix these two problems? Well, there are a couple of solutions.
First, we could just do the same thing on glasses with a projection system, so that the thing you are reading would be projected on the lens. However, it would still have the problem of the minimum eye focus distance. But, if it could project the illusion of looking far away, our eyes would be tricked to think that it was far away. What if you don't like wearing glasses? We could do the same thing for contacts, except making it that much further away.

So in conclusion, in a few decades, this could be on the general market, and you can finally have he world in your eyes.
