Astigmatism

astgmatismAstigmatism is a refractive condition in which the light rays entering the eye fail to form one clear point of focus on the sensory retina of the eye. This is most often caused by a cornea that is not symmetrically curved, but may also be secondary to trauma or a corneal condition called keratoconus. Symptoms of astigmatism include blurry or smeared vision, headaches or fatigue, and squinting. Treatments for astigmatism correction include glasses, contacts for astigmatism, or even LASIK. A comprehensive test for astigmatism is provided during every vision exam, but irregular or high degrees of astigmatism may require a more advanced diagnostic technique called corneal topography. Eye Care Center of Colorado Springs uses a topographer called the Orbscan II to assist with diagnosis and fitting of especially complicated contacts for astigmatism.

Each morning, residents of Colorado are greeted with a picturesque view of the majestic Rocky Mountains. While those who live on the Eastern Slope in Colorado Springs can look west at Pikes Peak, residents of Grand Junction can witness 13,000 foot peaks all around them on the Western Slope. However, thousands of people all throughout the state suffer from astigmatism, a condition that causes blurred vision. Astigmatism lenses help people combat this common disorder, but before we get into ways to treat this condition, it is important to understand the causes of astigmatism.

When humans look at something, the cornea, or surface of the eye, is responsible for putting the object in focus. Individuals who see clearly generally have corneas that are symmetrically curved, whereas the eyes of those with astigmatism have corneas that are not symmetrical.  There are many different causes for astigmatism including but not limited to:

  • Corneal scars, which can result from the healing of a past eye injury
  • Misshaping of the cornea as a result of eye surgery

Blurry vision isn’t the only symptom of astigmatism. Other indicators that you may suffer from this condition include squinting, headaches, and/or fatigue, which is why it is critical that you see an eye doctor if you are unsure whether or not you suffer from astigmatism.

Optometrists have a number of different ways of finding out if a patient needs astigmatism lenses or contacts. Eye charts (The Snellen Chart) are commonly used to reveal vision problems, but corneal topography is often used to find out how severely misshapen the cornea is.

There are a variety of different ways to treat astigmatism. Eye glasses or astigmatism contact lenses are surely the most common ways to combat the condition, and some individuals may choose to have refractive surgery (or LASIK).

For the residents of Colorado Springs, astigmatism contact lenses may be the answer to help you clearly see one of the most scenic backdrops in the country. Don’t let astigmatism hold you back from experiencing the true beauty of your home state.
