Eyes: Farsighted Correction

June 23, 2008 – 12:08 pm
The most common belief is that farsightedness (hyperopia) is caused by the eyeball being too short, from front to back. In some cases the cornea can be too flat or have too little curvature. In these types of cases, the treatments would involve prescription eyeglasses or contact lenses that are convex. Convex lenses would help bend the light correctly to compensate for the refractive error, and the focus would then be put directly on the retina. Patients who do not have any other eye problems, such as astigmatism, may only need to wear reading glasses.There are studies which show that children who experience hyperopia grow out of it. This raises some curiosity among theorists who look for other causes of the eye condition. Some believe eye problems, such as farsightedness, nearsightedness, or astigmatism may be a result of weak eye muscles. In this ...

Eyes: Causes Of Farsightedness

June 22, 2008 – 12:08 pm
There are a few different names for farsightedness, which include longsightedness, hypermetropia and hyperopia. The most common medical name is hyperopia. Like nearsightedness and astigmatism, farsightedness is a refractive error of the eye. This means the light rays that pass through the retina do not bend correctly to successfully transmit the images of the objects you look at to the brain. The light reaches a focal point behind the retina. Ideally, in a normally shaped eye, the light would refract directly on the retina. Nearsighted people experience blurred vision for faraway objects because the light refracts in front of the retina. On the other hand, farsighted people experience blurred vision of close up objects because the light refracts after it has already passed through the retina. Unlike nearsighted people with long corneal curvatures, farsighted people have eyeballs that are too short. ...

Eyes: Natural Improvement Of Vision

June 21, 2008 – 12:08 pm
A fairly substantial percentage of the optometrists and ophthalmologists in the world believe in studying and promoting the idea of natural vision improvement. One belief behind this theory of natural eye care is that eyesight can be improved with strengthening and relaxation techniques. In addition to eye exercises, many natural eye care supporters encourage healthy nutritional diets and a low stress lifestyle. Some also believe that glasses and contact lenses can encourage the eyes to become weak.There are numerous programs that are inspired by the philosophy that the eyes can heal naturally. Some programs may merely suggest a series of eye exercises to do on a daily basis. Some of these exercises may focus on eye muscle strengthening, while others focus on eyestrain or stress relief. The eye exercises are supposed to stimulate a concentration on eye muscle use that would usually be ignored ...

Eyes: Improve Vision Naturally

June 20, 2008 – 12:08 pm
Holistic approaches to eye care are becoming more common, and there are new programs developed and released to the public all the time. Before any type of medical practice can be addressed, we must first understand why we have vision problems. Our visual world is created by the light that passes through the retina. The brain processes the refracting of light and tells our eyes what we see. When there are problems with our eyes, the information sent back and forth between the brain and eyes is distorted, and visual problems occur.There are many ways to try and correct the misinformation passed to the brain and to improve vision. The most common approaches are prescription eyeglasses or contact lenses. Other treatments include different types of eye surgeries, where a reshaping of the cornea is done through cutting. The most common laser surgeries are ...

Eyes: Nearsighted Vision

June 19, 2008 – 12:08 pm
The medical term for nearsightedness is myopia. People who have nearsighted vision can see objects close to them, but objects that are far away, such as highway signs or billboards, will appear blurry. Myopia occurs because the light that enters the eye focuses in front of the retina instead of focusing on it. This is a result of an eyeball shape that is slightly longer than normal. Some children will experience this through growth stages, and the eyeball shape may even out with growth, resulting in improved vision. Another cause of myopia may be too much stress put on the corneas from long hours of close up vision work. Some people with nearsighted vision may experience symptoms early on. These can include blurry vision of far away objects, eyestrain, headaches, fatigue, eye soreness and squinting. About 30 percent of Americans experience myopia, ...
