What is Astigmatism?

Astigmatism, while a scary-sounding word, essentially means that the front of the eye (the cornea) is not perfectly round. Eyes that are perfectly round only need one power in their glasses or contact lens prescription to make them see clearly. Eyes with astigmatism, that are more oval-shaped, need two powers to provide them with clear vision. Most people have an astigmatism in one or both eyes, as it is very uncommon for someone to have a perfectly round cornea. At your next eye exam, if your eye doctor tells you that your prescription includes astigmatism, remember that most likely means you have a normal glasses prescription.
