What is Astigmatism? Understanding Causes and Treatments at Blue Fin Vision in London

What is astigmatism? This common refractive error affects millions of people worldwide. It occurs when the cornea or lens of the eye is irregularly shaped, leading to blurred or distorted vision at any distance. Unlike myopia (nearsightedness) or hyperopia (farsightedness), astigmatism can cause complications in both near and distant vision. Understanding What is Astigmatism? is essential for recognizing its symptoms, causes, and available treatments. At Blue Fin Vision in London, we are committed to providing comprehensive care for patients with this condition.

Understanding Astigmatism

To fully comprehend what is astigmatism?, it is crucial to explore its underlying causes. Astigmatism typically results from an irregular curvature of the cornea, the clear front surface of the eye, or the lens inside the eye. Instead of being perfectly round, the cornea may be shaped more like a football, causing light rays to focus at multiple points instead of a single point on the retina. This irregularity can lead to various vision problems.

Causes of Astigmatism

There are several factors that contribute to the development of astigmatism. When exploring what is astigmatism?, consider these common causes:

  1. Genetics: Astigmatism often runs in families, meaning that if your parents had the condition, you may be more likely to develop it as well.
  2. Eye Injury or Surgery: Trauma to the eye or previous eye surgery can lead to changes in the cornea’s shape, resulting in astigmatism.
  3. Keratoconus: This progressive condition causes the cornea to thin and bulge outward, further distorting vision and leading to astigmatism.
  4. Irregularities in Eye Structure: Conditions affecting the eye’s structure, such as certain diseases, can contribute to the development of astigmatism.

Understanding these causes is vital for recognizing what is astigmatism? and how it may affect your vision.

Symptoms of Astigmatism

Common symptoms of astigmatism include:

  • Blurred or distorted vision
  • Difficulty seeing at night
  • Eye strain or discomfort
  • Headaches
  • Squinting to see clearly

If you experience any of these symptoms, it’s important to seek an eye examination to determine whether you have astigmatism.

Diagnosing Astigmatism

To accurately answer the question, what is astigmatism?, a thorough eye examination is necessary. At Blue Fin Vision, our eye care professionals conduct various tests to evaluate your vision. The primary test for astigmatism is a refraction assessment, which measures how light rays are bent as they enter the eye. This test helps determine the type and degree of astigmatism you may have.

Treatments for Astigmatism

Once diagnosed, there are several treatment options available for astigmatism. Understanding what is astigmatism? includes knowing how it can be effectively managed:

  1. Prescription Eyeglasses: Special lenses can correct the refractive error caused by astigmatism, providing clear vision.
  2. Contact Lenses: Toric contact lenses are specifically designed for astigmatism and can provide improved visual acuity.
  3. Refractive Surgery: Procedures like LASIK or PRK can reshape the cornea, correcting astigmatism and reducing dependence on glasses or contact lenses.
  4. Orthokeratology: This non-surgical treatment involves wearing specialized contact lenses overnight to temporarily reshape the cornea, allowing for clear vision during the day.
