Most people are familiar with two common refractive errors in the eye: nearsightedness and farsightedness. Surprisingly, there's a third type of refractive error that can give you blurry vision, and it's called astigmatism. It's not an eye disease, but a problem your eye has in focusing light. This causes your vision to be out of focus in multiple ways in a single eye, requiring more than one prescription for correcting your vision.
When you have astigmatism your vision will tend to be blurred at all distances, in most cases. This generally causes patients to squint when trying to make out objects ahead of them. This can also cause headaches and eyestrain if it's left uncorrected.
In almost all cases, astigmatism is caused by an irregularly shaped cornea. The cornea is the part of the eye that focuses the light that passes through on the way to the retina at the back of the eye. This thin covering on the front of the eye is generally perfectly round, like a basketball. In cases of astigmatism, the circle flattens into more of an oval, giving the cornea more of a rounded football or oval appearance. This causes the light and images to focus at different depths within the eye, making images either more or less sharp. This means you can actually need multiple prescriptions to correct the vision in one single eye.
The first step in caring for your eyes is to determine if you really do have astigmatism. Our eye doctor will give you a comprehensive eye exam to find out what's needed to correct your vision. If he does determine that you have astigmatism, it's not a reason to worry; it's actually no more serious than being nearsighted or farsighted.
Once we find out the prescriptions needed to correct your vision, you'll consult with our eye doctor to decide what type of correction you prefer. The standard choice has been eyeglasses for many people. We can have special lenses made that correct your vision. A growing choice is specialty contact lenses. These lenses, called toric lenses, are specially made to correct different parts of the eye with different prescriptions. Since there is no problem with a gap in the peripheral vision, contact lenses may give you a better result than eyeglasses. One final choice is corrective surgery. LASIK and other surgeries can give you great results.
Correcting your astigmatism begins with a comprehensive eye exam. Give us a call to make an appointment. Contact us at (757) 229-1131 and we'll arrange a visit today.
