What Is Astigmatism?

Astigmatism is one of the most common vision conditions, caused by an irregular curvature of the cornea or lens. Instead of being round like a basketball, the eye is shaped more like a football, causing light to focus unevenly on the retina.

What Is Astigmatism?

Astigmatism is one of the most common vision conditions, caused by an irregular curvature of the cornea or lens. Instead of being round like a basketball, the eye is shaped more like a football, causing light to focus unevenly on the retina. This results in blurred or distorted vision at all distances. It almost always occurs alongside nearsightedness or farsightedness.

When to seek care

If you notice blurred or distorted vision, frequent headaches while reading or using a screen, or difficulty seeing at night, schedule a comprehensive eye exam — comprehensive exam. Astigmatism is easily diagnosed with a refraction test and corrected with the right prescription.

Symptoms of Astigmatism

  • Blurry, distorted, or fuzzy vision at all distances

  • eyestrain and discomfort

  • headaches, especially after reading or screen time

  • difficulty seeing at night

  • squinting to try to see clearly

  • eye fatigue.

Causes & Risk Factors

Astigmatism is usually present from birth and often hereditary. It may also develop after an eye injury, surgery, or as a result of keratoconus. Unlike the misconception that reading in dim light or sitting too close to a screen causes astigmatism — there is no evidence these habits affect the shape of the cornea.

Treatment Options

  1. Overview

    Prescription eyeglasses with a cylindrical lens correction; toric contact lenses (soft or rigid) designed to correct the irregular curvature; refractive surgery (LASIK, PRK, or LASEK) for eligible patients to permanently reshape the cornea; toric intraocular lenses (IOLs) used at the time of cataract surgery to address astigmatism.

Insurance & Cost for Astigmatism

Astigmatism correction with glasses or contact lenses is covered by most vision insurance plans as part of your annual eyewear benefit. Refractive surgery (LASIK or PRK) is considered elective and is not covered by vision or medical insurance, though FSA and HSA funds may be used. Typically covered: • Comprehensive eye exam including astigmatism refraction • Eyeglasses or toric contact lenses through vision plan allowance • Annual vision exam copay applies Often out-of-pocket: • LASIK, PRK, or other refractive surgery (elective) • Premium lens materials and coatings beyond plan allowance • Toric contact lens fitting fee (separate from exam on many plans)

Coverage varies by plan — we verify your benefits before treatment

Call before your visit and we will check your vision and medical benefits so there are no surprises.

Frequently Asked Questions About Astigmatism

Can astigmatism get worse over time?

Astigmatism can fluctuate, particularly in childhood and early adulthood, then stabilize in the mid-20s. Changes can also occur with keratoconus or eye injuries. Regular eye exams will track any changes.

Can I wear regular contact lenses with astigmatism?

Standard spherical contacts are not designed to correct astigmatism and may leave vision blurry. Toric contact lenses are specifically made for astigmatism and provide much sharper vision for most patients.

Does LASIK fix astigmatism?

Yes. LASIK can treat most types of astigmatism effectively in eligible candidates. Not everyone is a suitable candidate — your prescription, corneal thickness, and overall eye health are evaluated before surgery is recommended.

Is astigmatism correction covered by insurance?

Vision insurance typically covers glasses or toric contact lenses for astigmatism through your annual eyewear benefit. Refractive surgery is elective and not covered by insurance. Many patients use FSA or HSA funds for LASIK — ask us about your options.
