Astigmatism is a common refractive error that can affect your vision in various ways, and you need to know how to get the right treatment. At Wichita Optometry, your Wichita, Kansas, eye care providers recognize that navigating the world of eye health can sometimes feel overwhelming, so we wanted to address some frequently asked questions about this condition.
What Is Astigmatism?
Astigmatism is a refractive error caused by an irregular shape of the cornea or lens in the eye. Instead of being perfectly spherical, the cornea may have a more oval shape, leading to distorted or blurred vision at distances. This condition can occur alongside other refractive errors, such as nearsightedness (myopia) or farsightedness (hyperopia), and is common among people of all ages.
What Are the Symptoms of Astigmatism?
People with astigmatism may experience symptoms including blurred or distorted vision, difficulty seeing at night, eye strain, and headaches. Some people may also notice that their vision fluctuates, making it challenging to focus on objects. If you find yourself experiencing any of these symptoms, it is time to schedule an eye examination at Wichita Optometry.
How Is Astigmatism Diagnosed?
Diagnosing astigmatism typically involves a comprehensive eye examination conducted by an optometrist. One common test is keratometry, which measures the curvature of the cornea. Additionally, a refraction test will help determine the appropriate prescription for corrective lenses.
Can Astigmatism Be Corrected?
Yes, astigmatism can be corrected through various means. The most common methods include prescription eyeglasses or contact lenses designed specifically for astigmatism. These lenses compensate for the irregular shape of the cornea, allowing for clearer vision. In some cases, refractive surgery, such as LASIK or PRK, may be an option for people seeking a more permanent solution.
What Types of Lenses Are Available for Astigmatism?
For those with astigmatism, our Wichita, Kansas, office has specialized lenses available. Toric lenses are designed specifically to correct astigmatism and are available in both eyeglass and contact lens forms. These lenses have different powers in different meridians, allowing them to match the curvature of the cornea. Your optometrist can help determine the best lens option for your needs.
Is Astigmatism Hereditary?
Astigmatism can have a hereditary component, meaning it may run in families. If one or both parents have astigmatism, their children may be more likely to develop the condition. However, environmental factors and eye health can also play a role in the development of astigmatism, making it important to have regular eye examinations regardless of family history.
How Often Should I Have My Eyes Examined?
Regular eye examinations are essential for maintaining optimal eye health, especially if you have astigmatism or other refractive errors. It is generally recommended to have an eye exam every one to two years, but your optometrist may suggest more frequent visits based on your individual needs and any changes in your vision.
