Most people are aware of vision problems such as nearsightedness (myopia) and farsightedness (hyperopia). Myopia is a condition that causes your distance vision to become blurry, while hyperopia causes your near vision to become blurry. But did you know that there is another common refractive vision error called astigmatism?
In many cases, astigmatism is present from birth, and it is possible that it is hereditary. The severity of your astigmatism can change over time. In some cases, it can change for the better and you may experience an improvement in your vision. In other cases it may change for the worse, causing your vision to become increasingly blurry.
