Astigmatism is an impairment of the eye in which a portion of the lens or cornea has become irregularly curved. To put it simply, astigmatism simply means that one or both eyes are not perfectly round. A normal healthy eyeball is perfectly round, and when light enters it, the light is evenly distributed for clear vision. When the eye is not perfectly round, the light does not move through every part of the eye with equal ease, causing warped or blurry vision. In fact, the primary symptom of this condition is blurred vision.
What Causes Astigmatism?
Astigmatism is actually quite natural. Because nothing in this world is perfect, no eyeball can ever be perfectly round. Astigmatism only becomes a problem when it becomes pronounced enough that vision is impaired.
Those who are prone to experience vision-impairing levels of astigmatism will first notice blurry vision. Often, we assume that this is just eye strain, but if you frequently experience blurry vision, you may have astigmatism and should have your vision checked.
What is an Astigmatism Eye Exam?
Your Leawood optometrist can provide you with an eye exam that will determine whether or not you have or are developing astigmatism. During the exam, other eye conditions may be found which can then be treated as well. For example, you may find that you are nearsighted or farsighted, either of which is easily correctable.
How Will My Astigmatism be Treated?
If your optometrist does find that you are showing the signs of astigmatism, you may be a candidate for one of several corrective treatments. You may receive one of the following corrective measures
- Glasses: Exceedingly common, corrective lenses will restore your vision to normal while you wear them. Prices vary, and glasses are generally easy to take care of and they are easy to take on and off.
- Contact Lenses: For those who don’t like the idea of wearing glasses, contact lenses are an option. Care is more complex, and taking contacts on and off is more challenging.
- Refractive Surgery: Finally, there is the surgical route. Refractive surgery has a very high success rate and can restore vision to very close to 20/20 or better.
If on the other hand, if your optometrist decides you only have a small degree of astigmatism, as most people do, then you may not need any vision correction.
