Astigmatism
- In the normal eye, light enters through the cornea (the clear
front surface of the eye) and comes to a focus on the retina in
the back of the eye. Astigmatism occurs when the cornea is not
spherical in shape (like a baseball) and instead is longer in one
direction (like a football). This causes the light to focus in
more than one place within the eye, causing your vision to be
distorted or blurred. Astigmatism is often responsible for
starbursts, "ghosting" images, and halos or rings around lights at
night.EnVision Eye Care
