Reasons
Astigmatism is a refractive mistake, which suggests that light going into the eye doesn't concentrate specifically on the back of the eye (the retina). browse around this web-site is blurred vision.

Typically, the cornea as well as lens refract light precisely so that light signals are focused on the retina to produce clear, crisp pictures in the brain.
