    The possible treatments for Astigmatism are glasses, contact lenses, and even vision correction procedures. Almost all degrees of “normal” astigmatism can be corrected with properly prescribed eyeglasses or contact lenses. For a person with only a slight degree of astigmatism, corrective lenses may not be needed at all, as long as other conditions, such as near sightedness or farsightedness, are not present. If the astigmatism is moderate to high, however, corrective glasses or contact lenses are probably needed. The extapolated prevalence of Astigmatism in canada is about 5,378,140.
