What is Astigmatism?
Astigmatism is a common eye condition. It happens when the front surface of the eye, called the cornea, or the lens inside the eye, has an uneven shape. Because of this, light does not focus evenly on the retina. As a result, vision can become blurry or distorted. Many people want to know, “what is astigmatism?” Simply put, it is a type of refractive error, like nearsightedness or farsightedness. According to the World Health Organization, astigmatism affects people of all ages. However, it can often be corrected with glasses, contact lenses, or surgery.

Astigmatism symptoms can vary from person to person. However, some signs are more common. If you notice any of these, it may be time to check your eyes:
