What Does Astigmatism Mean?

Astigmatism is a common vision condition that affects people of all ages. It occurs when the cornea, the clear outer layer of the eye, is not perfectly round. This causes light to focus incorrectly on the retina, the light-sensitive tissue at the back of the eye. As a result, people with astigmatism may experience blurred or distorted vision.

Symptoms of Astigmatism

  • Blurred or distorted vision at all distances
  • Difficulty seeing fine details
  • Eyestrain
  • Headaches
  • Double vision

Causes of Astigmatism

Astigmatism is caused by an uneven curvature of the cornea. The cornea is normally round, but in people with astigmatism, it is more oval-shaped. This causes light to focus differently on the different parts of the retina, resulting in blurred or distorted vision.

Treatment Options for Astigmatism

There are several treatment options available for astigmatism, including:

  • Eyeglasses or contact lenses: Eyeglasses or contact lenses can correct astigmatism by changing the way light enters the eye. This can help to improve vision and reduce symptoms.
  • LASIK surgery: LASIK surgery is a laser eye surgery that can permanently correct astigmatism. During LASIK surgery, the surgeon uses a laser to reshape the cornea, making it more round. This can help to improve vision and reduce symptoms.
  • PRK surgery: PRK surgery is another type of laser eye surgery that can correct astigmatism. During PRK surgery, the surgeon removes the outer layer of the cornea and then uses a laser to reshape the underlying tissue. This can help to improve vision and reduce symptoms.

Conclusion

Astigmatism is a common vision condition that can affect people of all ages. It is caused by an uneven curvature of the cornea, which results in blurred or distorted vision. There are several treatment options available for astigmatism, including eyeglasses or contact lenses, LASIK surgery, and PRK surgery. Talk to your eye doctor to learn more about which treatment option is right for you.
