Are the eye muscles that cause astigmatic?

Eye muscles is not realted to astigmatic, instead of that, the irregular shape of cornea or lens can cause astigmatic. 1. If the cornea does not curve perfectly - if one half is flatter or steeper than the other - the light that hits it will not refract properly and the retina at the back of the eye will receive an imperfect image. The person will have blurred vision from that eye - astigmatism.2. The lens has variations in its curvature, rather than having a perfect curve, causing images to reach the back of the eye (retina) imperfectly. Most patients with lenticular astigmatism have a normally shaped cornea - the defect is only in the curvature of the lens. Source:http://www.medicalnewstoday.com/articles/158810.php.
