You often experience troubling vision symptoms that you deliberately choose to neglect, thinking they will pass and that there’s nothing much to worry about. Now, that’s something you really need to avoid to prevent whatever underlying vision condition you have from deteriorating. One of the most common vision problems you might encounter is blurry vision which is frequently caused by a refractive error called Astigmatism.
In this article, we are going to give you a quick overview on Astigmatism, what are its root causes, symptoms, and diagnosis techniques. We will also provide you with treatment solutions and some important things to keep in mind about this particular eye condition.
What is Astigmatism?
Astigmatism is when your vision is out of focus at any distance, near or far. According to the American Optometric Association, “Astigmatism occurs when the cornea is irregularly shaped or sometimes because of the curvature of the lens inside the eye, (…) preventing light from focusing properly on the retina”.
In simpler terms, imagine you’re looking at a light beam. If your cornea is round in shape, you would be able to see the light source very accurately and clearly. However, if the shape of your cornea is oval (or distorted), the light rays coming into your eye cannot converge in one focal point on the retina and rather disperse into several focal points to create a blur effect in front and beyond the retina. This is called Corneal Astigmatism. In the other case of Astigmatism known as Lenticular Astigmatism, it is the lens shape that is distorted not the cornea. In both cases your near and far eyesight is blurred.
The Main Causes of Astigmatism
The Symptoms of Astigmatism
Following years of research and studies, it has been found that Astigmatism often occurs concurrently with other eye conditions, more specifically nearsightedness and farsightedness. Therefore, if you have either of these two vision conditions, it would be a good idea to check your eyes for Astigmatism.
Astigmatism is mainly diagnosed by optometrists via a comprehensive eye checkup. The doctor can use several diagnosis methods all meant to determine your visual sharpness, clarity and acuity, in addition to observing how the eye focuses light. These methods include:
WithAstigmatism being a refractive error, it is often treated through prescription eyeglasses having special lenses with varying features depending on the age of the patient and the type of Astigmatism. In some other cases, contact lenses are prescribed to correct the condition.
