Astigmatism is one of the most common eye conditions, but it’s also one of the most misunderstood. If you’ve ever been told you can’t wear contacts with astigmatism or that too much screen time causes astigmatism, you’re not alone. These common misconceptions can cause confusion and prevent people from getting the care they need.
In a previous post, we explained what astigmatism is, how it’s diagnosed, and treatment options. In this follow-up, we’re focusing on the myths about astigmatism that we hear most often—and clearing them up with facts from eye care experts.
Myth #1: Astigmatism doesn’t change over time
The truth: Like many aspects of your vision, astigmatism can shift as your eyes develop and age. It may become more pronounced over time or change due to eye conditions like cataracts. Regular comprehensive eye exams help track these changes and keep your prescription up to date.
At Iowa Eye Center, we recommend annual checkups to ensure your vision correction— whether that’s glasses, contacts, or surgery—still meets your needs.
Myth #2: You can’t wear contact lenses with astigmatism
The truth: You absolutely can wear contacts if you have astigmatism. In fact, specially designed toric contact lenses are made just for that purpose. These lenses stay in place and correct the uneven curvature of your cornea to give you clear, stable vision.
Other options include rigid gas permeable (RGP) or hybrid lenses, which may be ideal for patients with moderate to severe astigmatism. If you’ve been told in the past that contacts weren’t an option, schedule a contact lens fitting to explore the newer technologies available today.
Myth #3: Astigmatism is caused by reading in the dark or sitting too close to the screen
The truth: You didn’t “cause” your astigmatism by watching TV too closely or reading without enough light. Astigmatism occurs when the cornea or lens has an irregular shape, which is usually something you’re born with. It’s a natural variation in eye anatomy, not something triggered by your habits.
While digital eye strain is real, it doesn’t lead to astigmatism. So go ahead and use your screen, just remember to follow the 20-20-20 rule to keep your eyes feeling fresh.
Myth #4: Astigmatism isn’t serious and doesn’t need treatment
The truth: Astigmatism varies in severity. Some people may not notice mild cases, but moderate to high astigmatism can cause significant issues like:
- Blurry or distorted vision
- Headaches
- Eye fatigue
- Difficulty with night driving or screen work
Ignoring astigmatism can lead to daily discomfort and reduced quality of life. The good news? It’s very treatable with glasses, contacts, or surgical correction.
Myth #5: LASIK can’t fix astigmatism
The truth: One of the most common LASIK myths is that it can’t treat astigmatism. But the reality is, LASIK and other forms of laser eye surgery—such as PRK—can correct many cases of astigmatism by reshaping the cornea.
If you’re nearsighted, farsighted, or have astigmatism, you may be a candidate for laser vision correction. A consultation with our ophthalmologists can help determine the best treatment for your vision and eye health.
Myth #6: Astigmatism is rare
The truth: Astigmatism is very common. According to the American Academy of Ophthalmology, most people have at least some degree of astigmatism. It often appears alongside other refractive errors like myopia (nearsightedness) or hyperopia (farsightedness), and may go unnoticed until a comprehensive eye exam reveals it.
