Astigmatism is an eye disorder that refers to a common imperfection in the curvature of your eye. In most cases, this disorder is treatable with the help of corrective lenses or surgery and/or laser treatments. However, in many cases, astigmatism is not pronounced enough to warrant corrective lenses or other treatments. Although, if you suffer from blurred vision, near-sightedness, farsightedness or any other common symptom, then it is important that you visit a renowned clinic such as Live Oak Ophthalmology in Wilmington, North Carolina to get a thorough eye check-up. To understand the common symptoms, it is important that its various causes are understood first.

Astigmatism is a condition that occurs when the curvature of your eye is mismatched. Generally, the surface of your eyes, also called cornea, inside of your eye or the eye lens have imperfections. Instead of being in the shape of a perfectly round curved ball, your eye might be in the shape of an egg or the back of a spoon. This makes the light hitting your eyes to bend more in one direction than the other, causing astigmatism.
There is no proven cause of this disorder. However, people are born with this imperfection. In some cases, an individual might develop astigmatism after eye surgery, eye infection or an injury to the eye. It does not occur because of eye stress by reading in low light or watching TV from a close distance. However, these habits can lead to other eye disorders.

You might notice a slight blurring in your vision.
