When you have good eyesight, light passes through an evenly curved cornea and refracts, allowing you to see clearly. However, surface issues involving the cornea can affect the retinal focusing. Surface issues like flattening and bulging can cause blurred vision, and astigmatism is often the cause. Astigmatism is actually quite common with approximately 45 million Americans having astigmatism. And the prevalence rates are high with around one and six Americans reporting the vision problem. Astigmatism commonly presents with vision issues such as myopia and hyperopia. And when myopia and hyperopia occur with severe astigmatism, eye doctors refer to this as refractive errors, according to the American Optometric Association. Though it remains

Interestingly, astigmatism has very few natural causes. In fact, the underlying cause of astigmatism is unknown. It is a hereditary vision issue that often occurs from birth. Astigmatism can also increase and decrease as you age. Chalazion is a benign nodule located in the upper or lower eyelid that has been associated with astigmatism. Scarring or an eye disease termed keratoconus may also cause astigmatism as well. However, the vision condition is often associated with myopia and hyperopia.

This occurs when light is bent in a different way when hitting the cornea. Those without astigmatism normally have a round cornea, but those with have more of a rugby ball or football shaped cornea. The amount of blurred vision varies, and often progresses as you age. However, you may have astigmatism and not even know it. The symptoms include blurred vision, eyestrain when looking at details, squinting, image distortion, and headaches. http://www.shutterstock.com/pic-204149095/stock-photo-astigmatism.html?src=Y6HeazT4D5fugScM-uOBaw-1-57

The exam and diagnosis is an easy process, and it can be detected during any routine eye exam from your ophthalmologist. Your eye doctor can detect astigmatism by checking your response to refractive lenses. Your eye doctor can also use a keratometer and topographer to check the thickness and curvature of your cornea.
