It is caused mainly due to irregular shape of the cornea or of the lens which is located behind the cornea and is called as lenticular astigmatism. The problem can be corrected by use of eyeglasses, contact lenses or refractive surgery.
To put it in lay man's term astigmatism means that the cornea is oval in shape instead of being spherical. The cornea in the astigmatism condition has two curves - a steeper and a flatter curve. This kind of curve spreads the light to two focus points instead of one, leading to blurred vision.
Astigmatism is said to be hereditary as many are born with oblong cornea. Being born with this defect can create problems for future. Astigmatism is also caused due to scarring of the cornea by performing certain type of eye surgery. It is also caused due to keratoconus - a disease which causes thinning of the cornea.
Astigmatism leads to nearsightedness (myopia) when the cornea is curved too much. The light which should be focused on the retina is focused in front of the retina leading to a blurry vision for distant objects. It also causes farsightedness (hyperopia), as the cornea is not properly curved. Here, the light is focused behind the back of your eye making nearby objects blurry.
You can detect the signs and symptoms of astigmatism when there is deformation in parts of the visual field. The horizontal, vertical or diagonal lines look blurred. It may seem to do less harm to you but if this condition worsens it is better to consult your doctor. If you are suffering from blurred vision or headaches, a doctor's consultation is very important. Rubbing or squinting is also a good sign to confer with your doctor. By practicing yoga the problem of astigmatism may lessen.
One of the most common types of surgeries used to correct astigmatism is the astigmatic keratotomy and LASIK. This kind of surgery reshapes the cornea which makes it right enough to focus on one point. The one thing that can be done to correct astigmatism is to get a surgery done as early as possible. Children are at risk to permanently loose their eyesight due to astigmatism. So the best solution for this is an early surgery.
What Causes Blurred Vision
Here we are in the age of speed. We want everything fast. Our food (and that could be another problem), our work and searching on the internet. Now where am I going with an article about blurred vision? With diabetes reaching epidemic proportions, more and more people like you and me are losing part or all of our sight.
How will you be able to live in a faster world when eyesight is so important if your vision keeps decreasing?
Diabetes is the number one culprit for vision loss and blurred vision in the United States. The American Academy of Ophthalmology claims that if you are a diabetic you have a 25 times more chance of losing your site or getting at least blurred vision than someone without this disease. I repeat a 25 times more chance of losing your sight with diabetes. This is scary.
Initially blurred vision may come and go as your blood sugar levels improve or get worse. But over time higher blood sugar levels start to damage the blood vessels in the back of the eye in the retina. The longer you have diabetes the more apt you are to have diabetic retinopathy.
Overwhelming high per cent age of diabetics, with poor control of their blood sugar levels develop negative changes in their eyesight within 15 years of the diabetes. You may think 15 years is a long time. But do you want to play around with your eyesight.
The two types of retinopathy are called Non-proliferative and Proliferative. With Proliferative being rarer and more severe. Non-proliferative or better known as retinopathy occurs when small retinal blood vessels break and leak. Seldom does it require any action to be taken unless it causes hazy central vision or straight lines looked curved.
Proliferative retinopathy the more serious of the two is an unusual growth of blood vessels inside the retina. Scarring or bleeding of these vessels can have grave consequences beyond blurred vision like partial vision loss or even blindness. Early detection will help. If found at the beginning laser surgery can stop the leaking but not reverse existing vision loss.
To start taking control of this potentially dangerous situation is to get control over your blood sugar levels. This is a must through diet, exercise and herbal remedies. Step two is to see your eye doctor at least once per year. If anything new shows up your eye doctor can see for herself any changes that may tip off any problems that may show up later. Now you can take some effective action before you start to lose your eyesight.
If you or your family is affected by this rising tidal wave of diabetes: take action now to reduce your risk of vision loss. Don't be a victim! I hope this article about blurred vision and vision loss will help you see for yourself what direction you need to take. I would hate to see anyone go blind that did not have to. With just a few simple procedures in place you can avoid any eyesight problems that could show up because of diabetes.
