Guide To Astigmatism

If you have been to the optometrist recently for an eye exam, they may have diagnosed you with something called astigmatism. While this condition is one of the most common eye conditions, it is also one of the most misunderstood. If you have been diagnosed with this condition, it might seem like this is a death sentence for your vision. Fortunately, it isn't because of the amount of research that has gone into helping patients with astigmatism get better vision despite this condition. At Carlson Tillisch in Mankato and New Ulm, we are here to help you understand exactly what this condition is.

What Is Astigmatism

Astigmatism is when the corneal membrane is stretched to an imperfect curve. This leads to a refractive error and how the eye interprets the light that reflects on it. In layman's terms, astigmatism occurs when the eye is not the typical round shape. If your eye is shaped more like a football than a tennis ball, the light will bend more in one direction than the other. 

What Are Astigmatism Symptoms

An eye doctor can tell that you have astigmatism when, during a test, you mention that something far away looks blurry or wavy. Additionally, you might only be able to see some objects when they are brought up close to you and have some issues. You might also experience eyestrain while reading in dim or low lighting as well as bright lighting that is ideal for reading. Other symptoms include headaches and trouble sleeping at night. Since dealing with the symptoms of astigmatism uses a lot of energy, it can lead to people experiencing migraines. 

What Causes Astigmatism To Worsen

There are a few causes that can cause your astigmatism to become worse. Some causes are continuing to read or do activities in poor lighting, aging, and not getting the proper treatment in time. During this process, the cornea may expand which can make it even more difficult to treat astigmatism. 

How Is Astigmatism Treated

The most common type of treatment for astigmatism is corrective lenses that are shaped specifically for astigmatism situations. The doctor may perform tests using multiple different tools for a vision test, refraction test, and keratometry, a machine designed to measure the curves of your cornea. From here, they will be able to give you prescriptive lenses that treat myopia and, eventually, the headaches that are associated with this condition.
