What is Astigmatism?

• Astigmatism is a frequent and usually treatable
  imperfection in the curvature of the eye that
  causes blurred distance and near vision.
• Astigmatism happens when either the front surface
  of the eye (cornea) or the lens inside the eye
  has mismatched curves. Rather than having one
  curve similar to a round ball, the surface is
  egg-shaped. It results in blurry vision at all
  distances.
• Astigmatism is often present at birth and might
  occur in combination with nearsightedness or
  farsightedness. Often, it is not pronounced
  enough to need corrective action. When it is,
  treatment options include corrective lenses or
  surgery.

• Causes of Astigmatism
• The eye has two structures with curved surfaces
  that bend (refract) light over the retina, which
  makes the images
• The cornea, the clear front surface of an eye
  along with the tear film
• The lens is a clear structure inside the eye that
  changes shape to help the eye focus on nearby
  objects
• In a perfectly shaped eye, each of these elements
  has a round curvature, similar to the surface of
  a smooth ball. A cornea or lens with such a
  curvature bends (refracts) all incoming light
  equally to make a sharply focused image directly
  on the retina at the back of the eye.
