Astigmatism Treatment

Symptoms

Signs and symptoms of astigmatism may include:

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

Causes

Your eye has two structures with curved surfaces that bend (refract) light onto the retina, which makes the images

  • The cornea, the clear front surface of your eye along with the tear film
  • The lens, a clear structure inside your eye that changes shape to help focus on near objects

In a perfectly shaped eye, each of these elements has a round curvature, like the surface of a smooth ball. A cornea and lens with such curvature bend (refract) all incoming light equally to make a sharply focused image directly on the retina, at the back of your eye.

More about Treatment

Astigmatism (uh-STIG-muh-tiz-um) is a common and generally treatable imperfection in the curvature of your eye that causes blurred distance and near vision.

Astigmatism occurs when either the front surface of your eye (cornea) or the lens, inside your eye, has mismatched curves. Instead of having one curve like a round ball, the surface is egg shaped. This causes blurred vision at all distances.

Astigmatism is often present at birth and may occur in combination with nearsightedness or farsightedness. Often it's not pronounced enough to require corrective action. When it is, your treatment options are corrective lenses or surgery.
