Astigmatism

Last reviewed: July 28, 2010.

Astigmatism is a type of refractive error of the eye. Refractive errors cause blurred vision and are the most common reason why a person goes to see an eye professional.
Other types of refractive errors are:

• Farsightedness
• Nearsightedness

Causes, incidence, and risk factors


People are able to see because the front part of the eye is able to bend (refract) light and point it to the back surface of the eye, called the retina.
Changes in the length of the eye, or the shape of either the lens or the cornea make it more difficult for the eyes to focus light. If the light rays are not clearly focused on the retina, the images you see may be blurry.
With astigmatism, the cornea (the clear tissue covering the front of the eye) is abnormally curved, causing vision to be out of focus.
The cause of astigmatism is unknown. It is usually present from birth, and often occurs together with nearsightedness or farsightedness.
Astigmatism is very common. It sometimes occurs after certain types of eye surgery, such as cataract surgery.

Symptoms


Astigmatism makes it difficult to see fine details, either close up or from a distance.

Signs and tests


Astigmatism is easily diagnosed by a standard eye exam with refraction test. Special tests are not usually required.
Children or others who cannot respond to a normal refraction test can have their refraction measured by a test that uses reflected light (retinoscopy).

Treatment


Mild astigmatism may not need to be corrected.
Glasses or contact lenses will correct astigmatism.
Laser surgery can help change the shape of the cornea surface to correct astigmatism, along with nearsightedness or farsightedness.

Expectations (prognosis)


The right glasses or contact lenses, or laser vision correction can usually correct vision to normal.

Complications


Uncorrected astigmatism in only one eye may cause amblyopia.

Calling your health care provider


Call for an appointment with your health care provider or ophthalmologist if vision problems worsen, or do not improve with glasses or contact lenses

Astigmatism Cure - How to Get Rid of Astigmatism Naturally

An uneven development in the cornea of the eye that results in poor eyesight is called astigmatism. In this condition, the cornea is no longer round, but becomes oval.




PRLog (Press Release) - Mar 02, 2010 - An uneven development in the cornea of the eye that results in poor eyesight is called astigmatism. In this condition, the cornea is no longer round, but becomes oval. Symptoms may be headaches, blurred vision and eye pain. The individual with astigmatism usually is treated with surgery or corrective lenses. An astigmatism cure that relies on natural remedies is much less traumatic.

Three main categories for improving vision naturally have gained significant approval. The first natural treatment is exercise. There are several exercises that can be used to improve vision and focus. Exercises such as yawning widely and rolling the eyes in a circular motion several times per day help to relax facial muscles. Change your focus from near to far rapidly and blink your eyes rapidly to reduce eyestrain.

An astigmatism cure that is based on diet is another popular remedy. Some of the foods that have been recommended include any foods that are high in antioxidants. Kale, peppers and cabbage are good examples. Berries such as acai, goji, and blueberries are also recommended. Carrots and carrot juice contain ingredients helpful to improve vision, especially when mixed with celery, cucumber, parsley and spinach.

Another type of remedy for astigmatism is herbal. These herbs can be applied to the eyes topically or as teas and other concoctions to be sipped. Two to three drops of rosewater mixed with lime juice in the eyes several times daily is one herbal example. Gentian root, pine bark extract and grape seed extract are examples of herbal remedies.

An astigmatism cure should be undertaken as early in life as possible to avoid further deterioration of eyesight. Some of the more exotic cures rely on mind body interaction that may not be realistic for young children. Changes in diet and doing the exercises can be done with help from a parent.
