The Impact of Astigmatism on Your Vision
Astigmatism is a common refractive error that affects millions of people worldwide. It occurs when the cornea or lens of the eye has an irregular shape. Normally, the cornea and lens are round, like a basketball, allowing light to enter the eye and focus on the retina. In the case of astigmatism, the cornea or lens is more oval-shaped, like a football, causing light to scatter and resulting in blurry or distorted vision.
For individuals with astigmatism, both near and distant vision can become a challenge. Straight lines may appear wavy, and objects might seem out of focus or doubled. Everyday tasks like reading a book, driving, or enjoying outdoor activities can become difficult, especially in low-light conditions. In severe cases, astigmatism can also cause headaches, eye strain, and fatigue due to the constant effort to focus.
At Southwest Eye Institute, we understand how astigmatism can impact daily life, and we’re here to help you find a solution that fits your lifestyle.
The Causes Behind Astigmatism
An irregular shape in the cornea or lens of the eye causes astigmatism. The cornea is the transparent outer layer that allows light to enter the eye, while the lens fine-tunes the light for clearer vision. When the cornea or lens is unevenly shaped, light does not focus properly on the retina, leading to blurry or distorted vision.
There are two main types of astigmatism:
- Corneal Astigmatism: The most common form occurs when the cornea has an uneven curve.
- Lenticular Astigmatism occurs when the lens inside the eye is irregularly shaped.
While astigmatism is often present from birth, it can develop over time due to aging, eye injury, or even previous eye surgery. Many people with astigmatism also have other refractive errors like nearsightedness (myopia) or farsightedness (hyperopia). If you suspect your vision is changing, visiting an eye care professional for a comprehensive exam is essential.
How Common Is Astigmatism?
Astigmatism is prevalent, affecting approximately 1 in 3 people in the United States. It is one of the most frequent refractive errors, alongside nearsightedness and farsightedness. Astigmatism can develop at any age but is often diagnosed during childhood or adolescence. Some people may have mild astigmatism that doesn’t significantly affect their daily life, while others may experience more severe symptoms that require treatment.
Whether you’re noticing gradual changes in your vision or simply want to ensure your eye health is on track, Southwest Eye Institute’s team of experts has many solutions to help you stay ahead of your eye care needs.
The Genetics of Astigmatism
Research has shown that genetics, or inherited traits, play a major role in whether you develop astigmatism. In fact, about 60% of the cause of astigmatism is related to your genes.
A recent study identified a specific gene, called VAX2, that may be linked to astigmatism. This gene is involved in the development of the eye, and this discovery gives us new insights into what causes astigmatism.
If one or both parents have astigmatism, their children will likely develop the condition. While it is possible to have astigmatism without a family history, many individuals inherit the irregular corneal or lens shape that leads to the condition.
Astigmatism can develop at any point in life, but if it’s present at birth, it may become more noticeable as children grow. Early detection is key, as untreated astigmatism can lead to complications such as amblyopia (lazy eye) in children.
Finding the Right Treatment for Astigmatism
Astigmatism can be corrected and the best option for you will depend on the condition’s severity, lifestyle, and vision goals.
1. Eyeglasses
For many people with astigmatism, the solution is as simple as wearing glasses or contact lenses. Specialized cylindrical lenses can correct the uneven curvature of the cornea or lens, providing clearer vision. Eyeglasses are the most common correction method, as they are easy to use and offer a straightforward solution.
2. Contact Lenses
Contact lenses are another option for those who prefer a more convenient or discreet solution. Toric contact lenses are specifically designed for individuals with astigmatism and are shaped to match the eye’s curvature. These lenses can provide a more stable and precise correction than regular spherical lenses.
3. LASIK Surgery
LASIK is a highly effective surgical option for correcting astigmatism. During the procedure, a laser is used to reshape the cornea, allowing light to enter the eye directly and focus on the retina. Most people with mild to moderate astigmatism are good candidates for LASIK. This surgery can provide long-lasting results, significantly reducing or even eliminating the need for glasses or contact lenses.
At Southwest Eye Institute, we offer FREE LASIK consultations to help you determine if this procedure is the right fit for you. Our team of experts will walk you through the process, answering any questions and providing guidance on what to expect before, during, and after the surgery.
4. Dual Benefits with Cataract Surgery
Cataract surgery provides a dual benefit for individuals with both cataracts and astigmatism. By removing the clouded natural lens and replacing it with a toric intraocular lens (IOL), the procedure can correct astigmatism while also improving vision affected by cataracts. This combined approach can reduce the need for corrective eyewear and significantly enhance visual clarity.
This approach can significantly improve your vision, reducing the need for glasses or contact lenses.
Can Astigmatism Go Away?
Astigmatism typically does not go away on its own, but its severity can remain stable or worsen over time. If left untreated, astigmatism can increase eye strain, discomfort, and difficulty with daily tasks. While corrective measures like glasses, contact lenses, or surgery can improve vision, the underlying irregularity of the cornea or lens remains unless addressed through treatment.
Why Your Astigmatism May Worsen
Several factors can contribute to the worsening of astigmatism over time. As we age, the shape of the cornea may naturally change, and astigmatism can become more pronounced. Eye injury, eye surgery, or certain medical conditions can also impact the shape of the cornea or lens, leading to a progression of astigmatism.
If you notice changes in your vision, scheduling an eye exam as soon as possible is important. Early detection and treatment can help prevent further deterioration of your vision.
