The Differences Between Vision And Eyesight

Many people are so used to seeing a blurry world or dealing with eyestrain. It is perfectly normal for those who sight problems to not see as clearly as they should and not know the difference. Once their vision is corrected they see a clearer world for the first time and things appear so much different and the strain has been released. Most people who have finally got their corrective lenses will experience much visual discomfort.

The world is blurry again and the eyes don’t want to strain to focus with out the eyewear. Technically it isn’t your vision that has changed it is your perception that has. Once seeing with out glasses was not an issue even when your site was not good, your brain had no comparison for difference. Now that you have had corrective lenses your brain acknowledges that the world is fuzzy when they are not on.

Your eye power does not get weaker with time as many people believe it does. When people get headaches and are tired from too much reading or staring a television or computer screen too long, it has nothing to do with actual eyesight. For some people using their eye muscles can actually improve sight and vision and the need for corrective lenses. Sitting too close or reading in the dark is not associated with worsening of vision it causes muscle strain. This is what in turn causes the headaches and tired feeling.

If you start wearing corrective eye wear with proper prescription, you can see things without any strain. To produce the natural effect of vision you can use contact lenses. With age you may need to have reading glasses you should not consider these as corrective. They should only be used for reading and watching television and should not be worn for any other activity. It is important to remember that disease such as cataracts are not corrected by eye wear, but by medical treatment. Know if it is corrective lenses you need or medical treatment by knowing your vision.

Glaucoma is another issue to worry about and those who are African-American have a higher risk factor. As a person ages the risk for glaucoma will increase. At first it is only the side or peripheral vision that is affected. It isn’t till the disease is well advanced that central vision is affected. Many people have no idea that they even have it till they go in for a yearly eye exam. This is a good reason to be seen as scheduled by your optometrist. It is the peripheral vision test that can detect glaucoma early. Where there are no symptoms like pain or discomfort, only an eye exam can be sure. This is the number one silent stealer of sight. Just because you have 20/20 vision and no pain does not mean you do not have glaucoma. The only way to know is to get an exam.

Most vision disorders and/or diseases are treated in at least one of 4 ways, corrective lenses, medications, surgery, or vision therapy. This will depend on what the actual cause for your vision problem and what it is affecting. Vision therapy has been proven to help such disorders as non-presbyopic eye focusing issues, binocular vision, ocular motility dysfunctions that affect eye movements, a turned eye, lazy eye, and perceptual-motor dysfunction. This treatment can help improve the musculature around and controlling the eyes to aid in better function and vision over time.
