Causes

Astigmatism, a common vision condition that affects an individual's ability to see clearly, particularly at night, is primarily caused by an irregularly shaped cornea or lens.

• Corneal Astigmatism
  

  The cornea is the clear, dome-shaped outer layer of the eye. In individuals with astigmatism, the cornea has an irregular curvature, causing light to scatter as it enters the eye. This scattering of light can lead to blurred or distorted vision, especially at night when pupils are dilated, allowing more light to enter the eye.

• Lenticular Astigmatism
  

  Lenticular astigmatism, though less common, occurs when the lens inside the eye has an irregular shape. The lens helps focus light onto the retina, the light-sensitive tissue at the back of the eye. An irregularly shaped lens can cause light to be scattered before it reaches the retina, resulting in blurred or distorted vision.

It is important to note that astigmatism can vary in severity, and some individuals may experience only mild symptoms, while others may have more significant vision impairment. Regular eye exams are crucial for detecting and managing astigmatism effectively, ensuring optimal vision quality and preventing potential complications.
