Astigmatism is a common problem that can cause blurred vision even after correcting for nearsightedness or farsightedness. However, our optometrist here at Fallas Family Vision in McDonough can provide a prescription that takes into account your astigmatism and helps you see clearly again.
What is Astigmatism?
Nearsightedness and farsightedness occur because the curve of the eye is too shallow or too steep, causing the image focused by the lens of your eye to be either in front of or behind the retina, instead of in just the right place. Astigmatism involves an irregular curve of the eye that causes light to focus in different places on the retina instead of as a single image. Many people with astigmatism are also nearsighted or farsighted, but it can occur alone.
People are usually born with astigmatism, although it can be the result of injury or eye disease. It is very common, with more than a quarter of children in one study having at least 1.0 diopter or more of astigmatism.
Symptoms and Diagnosis
The main symptom of astigmatism is blurred vision. Although, people may also experience eyestrain, headaches, and other problems related to attempting to compensate for the issue. Diagnosis is performed using either a manual or computerized refractive error test. This is the same general method used to determine whether you are nearsighted or farsighted and how much correction you may require. If your prescription has a cylinder power on it, it includes a correction for astigmatism.
How is Astigmatism Treated?
The most common method for treating astigmatism is with corrective lenses. Glasses can correct for astigmatism, as can certain types of contact lenses. Regular soft contact lenses cannot correct for astigmatism because they take on the shape of your eye, but special toric soft lenses can. Modern soft lenses that can correct astigmatism come in a variety of options, including daily disposables and more.
Rigid gas permeable (RGP) lenses can also correct for astigmatism because they retain their shape in your eye. Certain types of refractive surgery, such as LASIK, can also be used to treat astigmatism. Our optometry professionals would be glad to discuss your options for treatment at your next visit to our eye doctor.
