How Do Glasses and Contact Lenses Work?

One of the biggest questions people ask when they look into making the switch from glasses to contacts is, “How do glasses and contacts work?” We are all pretty familiar with the concept of having a lens that fits in your eye and provides you with some peripheral vision. Obviously, the part about having a lens rather than glasses is that your vision is not blocked by something on your eye itself like glasses would be. The other important thing to note here is that your eyes can see without the aid of a lens, but now you must learn how to get the information from the computer to your eyes.


The way the computer works is pretty simple

The computer screen is basically a magnifier that is attached to a computer that is plugged into your eye through a small plug. As you are looking at the computer screen you are sending signals from your eyes to the computer. The computer processes this information and sends this signal through the optic nerve, which is located in your eye in the back of the eye.


how the information is passed from the computer to your eyes

The optic nerve sends signals down this pathway until it reaches the part of your brain that stores and retrieves all of the information that was sent by your eyes. Your brain then processes the information and sends it to your eyes. This is basically how the information is passed from the computer to your eyes and how the information is displayed on the monitor. Of course, you will need a good enough computer system to make sure that your eyes are seeing everything correctly and to have a clear picture.

So, now that you know how glasses and contact lenses work, you can better understand how they should be used for you. When you wear glasses or contacts you are restricting your vision to only a small portion of the world. You are also constantly having to squint, which can lead to headaches, eye fatigue, and many other problems. On the other hand, when you use an eye-tracking system, you see information at the tip of your finger and be presented with the information at the point of your choice.


a system you don’t need to worry about using glasses or contacts

This kind of system uses two optical microphones and one computer to provide you with the information you are seeking. The computer does most of the work, processing the information and displaying it on your monitor. With such a system you no longer need to worry about using glasses or contacts because you are always going to have access to the information that you are seeking. Now all you have to do is look at the information on your monitor and select what you want to do. It really is that easy. And it is the kind of system that is needed for people who cannot remember where they put something or can’t remember which finger to place on a virtual dot.


How do glasses and contact lenses work?

With an eye-tracking system, you are going to find out the answer to that question the easy way. You will learn how the whole vision system works and how to use the vision system in your day-to-day life. You may not even need to purchase new contact lenses if you already have perfect vision. In fact, most people have perfect vision but some experience some problems with their eyesight. With the help of eye-tracking technology, you will be able to find out what problem you have, what causes it, and what you can do about it.
