Understanding Astigmatism: Causes, Symptoms, and Treatment

If you’ve ever been told you have astigmatism, you’re not alone. In fact, most people have at least a small degree of it. While the term may sound intimidating, astigmatism is simply a common vision condition that affects how your eyes focus light. With the right care, it can be easily managed.

What Is Astigmatism?

Astigmatism is an irregular curvature to the eye that results in blurred vision. It can occur from two different locations within the eye. The first being the cornea (the clear front surface of the eye), and the other is the lens inside the eye. Instead of being perfectly round like a basketball, the surface is more oval, like a football. This irregular curve prevents light from focusing properly on the retina, leading to blurred or distorted vision at all distances.

What Causes Astigmatism?

Astigmatism is usually something you’re born with, though it can also develop over time. Common causes include:

• Genetics – many people inherit astigmatism from their family.
• Eye injury or surgery – trauma or certain procedures can change the cornea’s shape.
• Keratoconus – a rare condition where the cornea thins and bulges into a cone shape, resulting in irregular astigmatism.
• Digital screens – It has been shown that laptops, computers, cell phones, and digital devices used up-close can induce astigmatism or cause it to worsen over time.

Common Symptoms of Astigmatism

The symptoms can vary depending on severity, but typical signs include:

• Blurred or fuzzy vision at all distances
• Squinting to see clearly
• Headaches or eye strain, especially after reading or screen use
• Difficulty seeing at night
• Glare, halos, and light scatter at night

If you experience these symptoms, it’s time for a comprehensive eye exam.

How Is Astigmatism Treated?

The good news is that astigmatism can be corrected with several effective options:

• Eyeglasses – the simplest and most common solution. Prescription eyeglasses are used to correct the vision from the uneven curvature. It only corrects your vision when wearing the lenses, it will not have any impact on making your astigmatism better or less.
• Contact Lenses – Toric contact lenses are designed to fit the unique shape of the eye and provide clear, stable vision.
• Orthokeratology (Ortho-K) – Specially designed rigid contact lenses worn overnight to temporarily reshape the cornea.
• Laser Vision Correction – Procedures like LASIK, PRK, and the EVO ICL, can permanently correct your vision for eligible patients.
