If you're one of the many people afflicted with astigmatism, you may be plagued by blurred vision even if you have no trace of myopia (nearsightedness), hyperopia (farsightedness), or a sight-impairing eye disease. This condition is caused by small, but significant, irregularities in one or both corneas. The good news is that astigmatism can be corrected, and not only through eyeglasses or LASIK surgery. Modern contact lenses can cope with astigmatism nicely, and we offer a variety of astigmatism contact lenses here at Lewis County Eye & Vision in Chehalis, WA.
What Is Astigmatism?
Astigmatism involves the incorrect refraction of incoming light. The problem occurs when pits or other deformities in the normally-smooth corneal curvature bend light in ways that distorts vision. Less commonly, astigmatism can originate in the lenses of the eyes instead of the corneas. Blurriness is usually the result. Unlike the close-up blurriness of hyperopia or the distance-vision blurriness of myopia, the blurriness of astigmatism is present at all distance levels.
The vision changes caused by astigmatism can be so subtle as to be unnoticeable, or they can be severe enough to pose distinct challenges to reading, driving, or performing other daily tasks. While the mildest forms of astigmatism can be corrected by regular soft contact lenses as well as eyeglasses, more serious corneal irregularities can create additional obstacles. That's because standard contact lenses are designed to conform to the contours of your corneas, and they also rotate on the eye as you blink, preventing consistent correction of specific areas on the corneas. There are, however, contact lenses specially designed to tackle the astigmatism challenge, and we have them at our Chehalis clinic.
Contact Lens Options at Our Optometry Center
Our optometry center performs comprehensive eye and vision exams to correct problems such as astigmatism. Refractive testing and the use of an eye chart can help us understand exactly how astigmatism is affecting your vision. Our techniques can reveal the patterns and directions of the corneal irregularities in relation to imaginary lines called meridians. If standard contacts cannot correct your astigmatism, we can fit you with:
- Soft contacts with a toric design (which prevents rotation)
- RGP contacts that maintain a constant curvature for optimal correction
- Hybrid contacts (featuring rigid centers and soft rims)
- Scleral contacts that vault over the entire cornea
