What is Astigmatism
Astigmatism affects the surface of the eye, giving an irregular curvature to the cornea. It is not a disease, but rather an irregularity in the shape the cornea of your eye. It causes light rays to be refracted or disturbed within the eye, because of this; Astigmatism is described as a refractive error. Astigmatism can occur alone, or with other refractive error conditions such as farsightedness or nearsightedness. There are several different symptoms, some of which may be more difficult to detect, so it’s important to have regular eye exams and visit your doctor if you experience any of these symptoms.

What causes Astigmatism
As we said before Astigmatism affects the shape of the cornea, which is normally small and curved so that light can be focused equally in all directions. The condition causes an increase in the curve of one area of the cornea which causes the distortion in the way the light is focused, means it can no longer focus light rays at a single point. All the rays are not usually blurred some remain focused, which is why images usually appear blurred or wavy.
You will notice that the blurring occurs at all distances that is both far and near. The degree to which the distortion occurs is an indication of the level of astigmatism and will determine the action needed to correct the condition. Surgery, laser treatment and corrective lenses are some of the options available to patients who experience this condition.
Astigmatism can be hereditary, it can also develop as you age and is commonly associated with other eye disease or conditions.
Treatment for astigmatism is dependent on the level and severity of the condition which is of course determined by the degree of the irregularity of the curve of the cornea. It also depends if the condition exists on its on own or in combination with other eye conditions or diseases. Failure to take the necessary steps to correct the condition can lead to further deterioration of your vision brought on by the constant eye strain which can cause headaches and nausea.
Astigmatism can be difficult to detect as the problem can increase slowly over time, causing a slow deterioration in your vision. Ask your eye doctor to perform the necessary tests to detect the condition, determine the degree of astigmatism present and the best treatment option for you. It is not difficult and so no one needs to suffer, you don’t need to live a blurred life astigmatism is easily treatable.
