Astigmatism

What Is Astigmatism?

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye. This irregular shape prevents light from focusing properly on the retina, the light-sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.

Symptoms of Astigmatism:

The symptoms of astigmatism can vary in each individual. Common signs include:

  • Blurred or distorted vision
  • Eyestrain or discomfort
  • Headaches
  • Squinting to see clearly
  • Difficulty with night vision

Treatment for Astigmatism:

Astigmatism can usually be corrected with eyeglasses, contact lenses, or refractive surgery. Options include:

  • Eyeglasses: The simplest and safest way to correct astigmatism. Special corrective lenses in glasses can help counteract the irregular shape of the cornea.
  • Contact Lenses: Like glasses, contact lenses can correct astigmatism. A variety of contact lenses are available, including toric lenses, which are made specifically for people with astigmatism.
  • Refractive Surgery: Procedures such as LASIK or PRK can reshape the cornea, thereby correcting the refractive error caused by astigmatism.

Regular eye exams are important for detecting astigmatism early and determining the appropriate treatment.

Prevention of Astigmatism:

Astigmatism is usually a condition you are born with or develop early in life. It’s not caused by certain behaviors or actions, such as reading in low light or sitting too close to the television, so it is not typically a preventable condition. However, regular eye exams are essential for early detection and effective management.
