There’s a lens at the front of each eye that captures and projects light onto the retina. When all is well with this lens — the cornea — you see clearly. Images are in focus both far away and close up, and you have no need for corrective lenses. However, if this lens becomes misshapen, images may become blurry. This happens because the cornea isn’t refracting light as it should and light isn’t landing on the retina in an exact way. At this point, you have developed a refractive error, such as myopia, hyperopia, or astigmatism. Each will affect how easily you can read, drive, or use your computer at work. While myopia or hyperopia makes it more difficult to see either close-up or far away, astigmatism affects both aspects of your vision. Your eye doctor in Champaign, IL, can diagnose and treat astigmatism.
What Causes Astigmatism?
Several factors may cause your cornea to change shape. These include:
- Genetic Predisposition
- Eye Trauma
- Prior Eye Surgery
- Diseases of the Eye, Such as Keratoconus
If you’re experiencing problems with vision clarity, you may have astigmatism. Keeping regular appointments with your vision specialist may provide you with early diagnosis and intervention.
How Do I Know if I Have Astigmatism?
If your eyes frequently hurt, or if they feel strained, a refractive error such as astigmatism could be the culprit. Other common symptoms include headaches, blurred vision, and the inability to see images that are close up or far away without squinting. If it feels more difficult to drive, read, or look at the whiteboard in your classroom or at work, it’s time to book an appointment for a routine eye exam.
