Astigmatism

If you have blurred vision when looking at objects up close, far away, and in between, it may be astigmatism. Astigmatism causes blurry vision due to an irregularly shaped cornea. Most people have some slight astigmatism but not always enough to cause vision problems.

Your Cornea and Astigmatism

Astigmatism is a type of refractive error. Your cornea bends, or refracts, light as it enters your eye to focus it on the retina. In order to properly focus the light, your eye needs to be spherical in shape. With astigmatism, the cornea is oblong or oval shaped, more like a football. When the irregularly shaped cornea bends the light it creates two or more focal points, rather than one clear focal point, causing the image to be blurry.

Recognizing Astigmatism

Astigmatism can occur alone or in combination with nearsightedness (myopia) or farsightedness (hyperopia). Symptoms include:

  • Distortions in vision making it difficult to make out fine details up close, far away, and in between
  • Blurred vision
  • Eye strain
  • Headaches

Children can be born with astigmatism, or the condition can be caused by trauma to the eye due to an injury or surgery. Keratoconus is a disease of the eye that causes progressive thinning of the cornea and can cause astigmatism.

If you are experiencing the symptoms of astigmatism or any change in your vision, it is important to see your ophthalmologist right away. These can be symptoms of a more serious eye condition or health problem.

Astigmatism in One Eye

When vision is different between your two eyes, your brain chooses the better of the two images, ignoring the bad eye. The eyes do not work together properly and depth perception is affected.

In young children, whose brains are still developing, astigmatism in just one eye can cause lazy eye (amblyopia). Left untreated amblyopia can cause permanent vision loss in the affected eye.

Correcting Astigmatism

Eyeglasses or contact lenses are typically prescribed for people with astigmatism. In the past, soft contact lenses were not an option for astigmatism. Today there are soft contacts available for astigmatism, but they are more difficult to make and cost more than other soft lenses.

Corrective lenses improve your vision while you wear them, but they do not truly correct the astigmatism. Refractive surgery, such as LASIK or PRK, reshapes your cornea correcting the refractive error. If you are also nearsighted or farsighted, the surgery can correct that at the same time, giving you clear vision without the need for glasses or contacts.

Some Side Effects of Wearing Contact Lens are to the Disappointment of Users

The buildup of intraocular fluid on contact lenses is a possible side effect to the eyes. Lenses with such deposits are uncomfortable to wear. Users of these lenses are at risk of an eye infection. Soft contact lenses are prone to developing deposits of intraocular fluid more than hard contact lenses.

Such problems as swelling of the eyes and vision haziness that are associated with the cornea, off and on result from the use of contact lens. Lenses barricade the flow of oxygen to the corneas resulting in a condition called hypoxia. Users can suffer scrapes and scratches from lenses to their corneas. Bacterial Keratitis is a corneal infection that can result from the all time use of both soft and hard contact lenses.

Persons using lenses most of the time may suffer from inflammation of the eyelids. In some cases, inflammatory bumps appear under the eyelids. They are small but painful. Persons affected with eyelid inflammation have a painful experience of wearing contact lenses.

Developing dry eyes is one of the most common side effects that contact lens is known to have. Lenses absorb a little of fluid from the surface of the eyes and as a result, leave them dry. Users of both soft and hard contact lenses are similarly prone to having dry eyes. Severe symptoms like itching or burning sensation, redness, excessive tearing and swelling surface in case of persons with dry eyes.

People who wear lenses may also experience a kind of allergic reaction. Turning of the eyes red when lenses are inserted is a common allergic reaction. Such an allergic reaction subjects the eyes to hypersensitivity that results from the preservative used in contact lens solutions. Solutions with a different preservative are prescribed for persons with allergic reaction from lenses.
