Can You Develop Astigmatism As An Adult?

Astigmatism can develop at any age, including adulthood, due to changes in the eye’s shape or injury.

Understanding Astigmatism and Its Onset

Astigmatism is a common refractive error where the eye’s cornea or lens has an irregular curvature. Instead of being perfectly round like a basketball, the cornea or lens resembles more of a football shape. This uneven curvature causes light entering the eye to scatter or focus unevenly, resulting in blurred or distorted vision.

Many people associate astigmatism with childhood or early life since it often develops during those years. However, the question arises: Can you develop astigmatism as an adult? The answer is yes. While some cases are congenital or develop early, astigmatism can indeed manifest later in life due to several factors.

How Astigmatism Develops in Adults

Adult-onset astigmatism often results from changes in the eye’s structure over time. The cornea and lens can alter their shape due to aging, trauma, surgery, or certain medical conditions. These changes may cause new irregularities in curvature that were not present before.

Aging naturally affects the elasticity and thickness of ocular tissues. The cornea may become less flexible or slightly warped, leading to astigmatic changes. Similarly, cataract formation and subsequent surgeries can induce astigmatism by altering the lens shape or position.

Trauma is another contributor. Injuries such as corneal scratches, scars, or blunt force trauma can distort the corneal surface. Even minor injuries that heal asymmetrically may result in astigmatic vision problems.

Certain eye diseases like keratoconus—a progressive thinning of the cornea—can also begin during adulthood and cause significant astigmatism.

Common Causes of Adult-Onset Astigmatism

Aging: Natural tissue changes alter corneal curvature.
Eye Surgery: Procedures like LASIK or cataract surgery may induce astigmatism.
Injury: Trauma causes scarring and irregularities on the cornea.
Keratoconus: Progressive disease leading to corneal thinning and distortion.
Diseases: Conditions such as pterygium or infections that affect corneal shape.

Symptoms Indicating Adult-Onset Astigmatism

Recognizing new symptoms is crucial for prompt diagnosis and management. Adults developing astigmatism often notice:

Blurred vision, especially at all distances.
Distorted images, where straight lines appear wavy or bent.
Eye strain, headaches, or discomfort after visual tasks.
Difficulty seeing at night, including halos around lights.
Sensitivity to light.

These symptoms might appear gradually or suddenly depending on the cause. For example, trauma-induced astigmatism might cause immediate blurring, whereas age-related changes develop slowly over months or years.

The Importance of Regular Eye Exams for Adults

Since adult-onset astigmatism can sneak up unnoticed initially, regular comprehensive eye exams are critical. Eye care professionals use tools like keratometry and corneal topography to map the cornea’s shape precisely.

Detecting subtle changes early allows for timely corrective measures before symptoms worsen and impact daily life significantly.

Treatment Options for Adult-Acquired Astigmatism

Fortunately, adult-onset astigmatism is highly treatable with various options tailored to individual needs and severity.

Eyeglasses and Contact Lenses

Prescription glasses with cylindrical lenses are the simplest solution. They compensate for uneven focusing by adjusting how light bends entering the eye.

Contact lenses offer more customized correction:

Toric soft lenses: Designed specifically for astigmatism with different curvatures on different axes.
Rigid gas permeable (RGP) lenses: Provide sharper vision by creating a smooth refractive surface over an irregular cornea.
Scleral lenses: Larger lenses that vault over the entire cornea are excellent for severe cases like keratoconus.

Surgical Interventions

For more permanent correction or when glasses/contact lenses aren’t sufficient:

LASIK/PRK: Laser surgeries reshape the cornea to correct irregular curvatures causing astigmatism.
Limbal relaxing incisions (LRI): Small cuts made on the peripheral cornea to reduce curvature irregularities.
Cataract surgery with toric intraocular lenses (IOLs): Replaces cloudy lens while correcting pre-existing astigmatism simultaneously.
Corneal cross-linking: Used primarily for keratoconus to stabilize progressive thinning.

Each surgical option has risks and benefits; thorough consultation with an ophthalmologist is essential before deciding on these procedures.

The Impact of Lifestyle and Health Factors on Adult Astigmatism

Certain lifestyle choices and health conditions influence whether you might develop astigmatism later in life.

Eye rubbing: Frequent vigorous rubbing can distort the cornea over time.
Nutritional deficiencies: Poor vitamin intake may affect eye health indirectly.
Diseases like diabetes: Can cause fluctuating vision due to changes in lens hydration but also predispose eyes to structural issues.
Poorly managed dry eye syndrome: Can alter tear film stability affecting vision clarity temporarily but also contribute to discomfort that leads to rubbing damage.

Maintaining good ocular hygiene and managing systemic health conditions reduces risks linked with adult-onset refractive errors including astigmatism.

A Quick Comparison: Childhood vs Adult-Onset Astigmatism

	Childhood Astigmatism	Adult-Onset Astigmatism
Main Cause(s)	Congenital irregularities; genetic factors; developmental anomalies.	Aging changes; trauma; surgery; diseases like keratoconus.
Treatment Approach	Pediatric glasses/contact lenses; monitoring visual development; sometimes surgery if severe.	Spectacles/contact lenses; laser surgery; cataract surgery with toric IOLs; other interventions based on cause.
Symptom Onset Speed	Smooth onset during early childhood growth stages.	Smooth gradual onset or sudden if injury-related.
Lifelong Impact	Tends to persist through life unless corrected surgically or with corrective lenses; may stabilize after adolescence.	Might worsen if underlying causes progress (e.g., keratoconus); treatment often needed upon diagnosis regardless of age.
