What is astigmatism? Astigmatism is a medical term for an obscured vision that is brought on by the uneven contour of the cornea. In this problem light rays will get in the eye not in the best focus on the retina, developing a blurred photo. In easy words, astigmatism is a picture distortion that is triggered by incorrect form of the cornea. There are two sorts of astigmatism: corneal astigmatism that is triggered by an uneven form of the cornea and ventricular astigmatism which is brought on by an irregular shape of the lens.
What causes astigmatism? In corneal astigmatism, the light that enters into the cornea does not refract correctly creating the retina obtain an imperfect image. In ventricular astigmatism, the uneven shape of the lenses is responsible for the incomplete photos that get to the rear of the eye retina. What are the signs and symptoms of astigmatism?
