Your vision has felt off lately. Things look blurry whether you’re reading up close or looking across the room. Headaches are creeping in by mid-afternoon, and nighttime driving has become harder than it used to be. If any of that sounds familiar, astigmatism might be part of the picture. Prairie Vision helps families in Wainwright and Vermilion understand what’s driving these changes and what to do about them. The team offers comprehensive eye exams for adults and seniors to catch shifts in your vision before they start affecting your daily life.
Astigmatism can get worse over time due to factors like genetics, natural aging, untreated refractive errors, and certain eye conditions, but regular eye exams and the right correction can help manage it.
What Astigmatism Actually Is
Your eye needs to focus light precisely onto the retina to produce a clear image. With astigmatism, the cornea or lens has an irregular shape, so light scatters instead of landing in one sharp point. Think of it like a football versus a basketball. A perfectly round surface focuses light evenly, but an uneven curve sends it in different directions.
This scattered light is what makes things look blurry or distorted. Astigmatism often shows up alongside nearsightedness or farsightedness, which means you might be dealing with more than one refractive error at the same time. That’s exactly why getting a thorough eye exam matters so much. You can learn more about how these two conditions compare by reading about myopia vs. hyperopia.
Signs You Might Have Astigmatism
Astigmatism doesn’t always announce itself with obvious, dramatic symptoms. Sometimes it’s subtle enough that you adjust without realizing something is wrong. Here are some common signs to watch for:
- Blurry or distorted vision at any distance
- Frequent headaches or eye strain, especially after reading or screen time
- Trouble seeing clearly at night or in low-light situations
Children are especially likely to miss these signs because they don’t have a clear baseline for what sharp vision looks like. If your child is squinting, sitting too close to screens, or complaining of headaches, a children’s eye exam can help figure out what’s going on.
Reasons Astigmatism Can Get Worse
Family History & Genetics
The shape of your cornea is partly determined by genetics. If astigmatism runs in your family, your cornea may naturally develop a more irregular curve. This doesn’t mean worsening vision is unavoidable, but it does mean the risk is higher. Knowing your family history gives the doctor important context when monitoring your eyes over time.
Age-Related Eye Changes
Your eyes change as you get older, and those changes can affect astigmatism. The lens inside your eye gradually loses flexibility, and the shape of your cornea can shift as the years pass. These are natural processes, not anything you’ve done wrong. Staying on top of regular eye exams helps catch these shifts early, so your prescription can be updated before your vision suffers. The American Optometric Association recommends eye exams every one to two years for adults to stay ahead of these kinds of changes.
Untreated Refractive Errors & Other Eye Conditions
When astigmatism goes uncorrected, your eyes work harder to compensate for the blurry focus. That extra strain can make things worse over time. Certain eye conditions can also play a role. Keratoconus, for example, is a condition where the cornea gradually thins and bulges outward, leading to irregular astigmatism that becomes harder to correct with standard lenses.
Chronic eye rubbing is another factor worth noting. Rubbing your eyes frequently and forcefully can gradually alter the shape of the cornea, especially in people who are already prone to corneal irregularities.
Other Factors That Can Affect Astigmatism
Beyond genetics and aging, a few external factors can shift how astigmatism behaves. Eye injuries or trauma can change the shape of the cornea, sometimes in ways that increase astigmatism. Certain types of eye surgery can also have an effect, which is why a thorough pre-surgical evaluation matters.
An outdated or inaccurate prescription is another common issue. When your glasses or contacts don’t match your actual prescription, your eyes are constantly straining to compensate. That ongoing strain adds up over time and can make astigmatism feel more significant than it needs to be. If you’re overdue for an update, learning how often you should get an eye exam is a helpful place to start.
Treatment Options & Eye Care in Wainwright & Vermilion
Common Correction Options
Astigmatism responds well to correction when it’s properly diagnosed. Prescription glasses with specially shaped lenses can redirect light to focus correctly on the retina. Toric contact lenses are designed specifically for astigmatism and offer a comfortable alternative for those who prefer contacts over glasses. You can explore contact lens exams, fittings, and lens options to find out what suits your eyes.
For those looking at longer-term options, laser refractive surgery can reshape the cornea in eligible patients to reduce or eliminate astigmatism. Orthokeratology involves wearing specially designed lenses overnight to gently reshape the cornea, and it’s another option worth asking about, particularly for younger patients. The team can walk you through a laser eye surgery consultation to help you decide if that path makes sense for you.
The Role of Regular Eye Exams
Catching changes in astigmatism early makes a real difference. When the doctor monitors your prescription regularly, small shifts can be corrected before they start affecting your daily life. For kids, this is especially important since children rarely recognize that their vision has changed.
