There are a few common refractive errors. Myopia, also known as nearsightedness, make objects in the distance appear blurry. Hyperopia, also known as farsightedness, is another common one. This refractive error makes it difficult to see objects that are close. Astigmatism can affect both your closeup and far away vision and can make objects look distorted.
Astigmatism is not as common as nearsightedness and farsightedness, but about 8.4 percent of the population has it. Fortunately, the professionals at Today's Vision Creekside can treat the refractive error, helping you to see more clearly.
What Is Astigmatism?
Astigmatism occurs when your cornea is curved more steeply in one direction than the other. These mismatched curves can make it difficult to see clearly. Astigmatism can be present at birth, but you can get it later in life due to an eye injury, disease, or eye surgery. Some people believe that sitting too close to the TV, reading in poor light, and squinting frequently can cause astigmatism, but these are just old wives' tales. Time is what causes astigmatism to worsen.
The symptoms of astigmatism can make seeing difficult without correction. The more curved the cornea is, the higher correction you will need. The symptoms of astigmatism include:
- Blurry vision
- Distorted vision
- Needing to squint to see correctly
- Trouble seeing at night
How Is Astigmatism Diagnosed?
If you want to know how bad your astigmatism is, there is no special astigmatism test. Your eye doctor can diagnose astigmatism during your annual eye exam. The eye doctor will have you read the eye chart to see how well you can see. If you are not able to see well, they will dilate your eyes to examine the health and shape of your cornea. During this dilated check, the doctor can diagnose astigmatism.
How To Correct Astigmatism
There are a few different treatment options for astigmatism. These include:
- Eyeglasses: Your optometrist can give you an eye prescription for eyeglasses to correct the vision issues associated with astigmatism.
- Contact lenses: Many people prefer contacts over glasses because they provide a more natural appearance. Also, with contacts, you do not need to worry about an eyeglass frame or dirty lenses obscuring your view. If you have astigmatism, you will not be able to wear a traditional soft lens. Your eye doctor would need to fit you with a special lens called a toric lens. These are the best contacts for treating astigmatism.
- Lasik surgery: Lasik is a laser surgical procedure that can gently reshape your cornea, which will correct your refractive error. If you are going to be a good candidate, your eyes need to have matured and been free of disease. You need to be in good health and not pregnant or nursing. Finally, if you have astigmatism, your prescription can be no higher than 5.00. After the procedure and when your eyes have healed, you will no longer need glasses or contacts to see clearly.
