how can astigmatism affect your eye
What does this mean exactly? Astigmatism is a very common vision problem and one that should be discussed with your optometrist. It causes blurred vision at any distance when the irregular shaped cornea or lens prevents light from focusing properly on the retina at the back of the eye. The cornea and lens are primarily responsible for properly focusing light from entering your eyes to allow clear vision. The coordination of the eye movement depends on those eye muscles and nerves working together. A person's eye is naturally shaped like a sphere.
