Astigmatism is Natural

Astigmatism is an eye condition that is more common than you might think. According to Dr. Caster, almost everyone with farsightedness and nearsightedness has a little fragment of this problem. When you have astigmatism, you see things a little bit blurry and hazy. As a result, you might suffer from fatigue or headaches as a result of having to strain your sight.

What Causes It?

These are the two ways to develop astigmatism.

  • An irregularly shaped cornea. Your cornea should be as round as a globe, almost perfectly so. However, for a person with astigmatism, their eyes are more elongated. So, when light comes in, the astigmatic eye refracts the beams in multiple directions and, thus, distorting your vision.

  • Imperfectly shaped lens. Known as lenticular astigmatism, this is similar to the other, but in this case, your lenses are responsible for reflecting light improperly. Both turn up the same result.


While developing astigmatism is nothing out of the ordinary, there is such a thing as an irregular one. An eye injury can cause it, as well as certain types of eye surgery and diseases. For the latter, the most prominent case would be keratoconus, which causes the cornea to become thin overtime. Fortunately, there’s a cure.
