Astigmatism is a common vision condition that affects millions of people worldwide. It occurs when the cornea or lens of the eye has an irregular shape, leading to blurred or distorted vision. While mild astigmatism may not require immediate correction, higher levels can impact daily activities and may necessitate glasses or other treatments. In this guide, we’ll cover how to identify astigmatism, when glasses are necessary, holistic options, and available treatment methods.
How to Tell If You Have Astigmatism
Astigmatism symptoms can vary in intensity depending on the degree of corneal irregularity. Common signs include:
Blurry or distorted vision – Objects at any distance may appear stretched or wavy.
Frequent headaches – Straining to see clearly can lead to persistent headaches.
Eye strain or discomfort – Individuals often experience tired eyes, especially after reading or using screens for extended periods.
Difficulty seeing at night – Halos, glare, or starburst effects around lights are common.
Squinting to see clearly – People with astigmatism unconsciously squint to improve focus.
How to Check for Astigmatism:
If you experience these symptoms, optometrists at Caruso Eye Care can determine whether you have astigmatism through a comprehensive eye exam. They perform a refraction test using a phoropter or an autorefractor to measure the curvature of your eye and assess the level of correction needed.

What Level of Astigmatism Requires Glasses?
Astigmatism is measured in diopters (D), a unit that quantifies the optical power of corrective lenses. The levels of astigmatism typically fall into these categories:
Mild Astigmatism (0.25D - 1.00D) – Usually does not require correction unless symptoms affect vision quality.
Moderate Astigmatism (1.00D - 2.00D) – May need corrective lenses for optimal vision.
Severe Astigmatism (2.00D - 4.00D) – Glasses or contact lenses are generally necessary for clear vision.
High Astigmatism (4.00D or more) – Specialized lenses or surgical options may be recommended.
📌 Reference: The American Optometric Association (AOA) notes that individuals with astigmatism above 1.00D often benefit from glasses or contact lenses for sharper vision and reduced eye strain. (AOA Source)
Optometrists at Caruso Eye Care can assess your prescription and provide the best corrective lenses tailored to your needs.
Holistic Options for Astigmatism Management
While traditional methods like glasses and contacts provide the most immediate and effective correction, some individuals seek holistic approaches to manage mild astigmatism and overall eye health.
1. Eye Exercises
Some eye exercises claim to improve focus and strengthen eye muscles, though scientific support is limited. Popular exercises include:
Palming technique – Covering the eyes with warm palms to relax them.
Focus shifting – Alternating focus between near and distant objects to reduce strain.
Figure-eight movement – Tracing a figure-eight pattern with the eyes to improve flexibility.
2. Nutrition for Eye Health
Certain nutrients support overall eye health and may help prevent worsening vision conditions:
Omega-3 fatty acids (found in fish, flaxseeds, and walnuts)
Vitamin A (found in carrots, sweet potatoes, and leafy greens)
Lutein and Zeaxanthin (found in eggs, corn, and spinach)
3. Reducing Digital Eye Strain
Excessive screen time can exacerbate symptoms of astigmatism. Following the 20-20-20 rule (looking away from the screen every 20 minutes at an object 20 feet away for 20 seconds) may help reduce strain.
📌 Reference: Studies in the British Journal of Ophthalmology suggest that proper nutrition and screen management may play a role in maintaining eye health and preventing worsening of refractive errors. (BJO Source)
If you have concerns about your eye strain or diet's impact on vision, optometrists at Caruso Eye Care can provide guidance on lifestyle changes to support your eye health.
Astigmatism Treatment Options
For individuals requiring correction beyond holistic methods, several treatment options are available at optical centers, including:
1. Prescription Glasses
The most common and affordable option.
Corrects both astigmatism and other refractive errors like nearsightedness or farsightedness.
Optometrists at Caruso Eye Care can prescribe customized lenses based on your needs.
2. Contact Lenses
Toric lenses – Specially designed soft lenses that correct astigmatism.
Rigid Gas Permeable (RGP) lenses – Provide sharper vision for higher levels of astigmatism.
Hybrid lenses – Combine the benefits of RGP clarity with soft lens comfort.
3. Orthokeratology (Ortho-K)
Special rigid lenses worn overnight to temporarily reshape the cornea.
Effective for moderate astigmatism but requires continuous use.
4. Laser Eye Surgery (LASIK or PRK)
Reshapes the cornea to permanently correct vision.
Best suited for individuals with stable prescriptions.
📌 Reference: The FDA and the National Eye Institute confirm that LASIK has a high success rate in correcting mild to moderate astigmatism, with 90-95% of patients achieving 20/20 vision. (FDA Source)
If you’re considering contact lenses or laser surgery, optometrists at Caruso Eye Care can evaluate your suitability for different treatment options and recommend the best approach for your vision.
Conclusion: Taking the Next Step
If you suspect you have astigmatism, an eye exam is the best way to determine the appropriate correction method. Whether you choose glasses, contact lenses, or consider holistic management strategies, maintaining routine eye care ensures optimal vision.
For professional guidance, optometrists at Caruso Eye Care are available to provide comprehensive eye exams, discuss treatment options, and help you achieve clearer vision.
