Astigmatism: Causes and Symptoms
Astigmatism is a very common eye condition that’s easily corrected with eyeglasses or contact lenses and on some occasions, surgery.
Astigmatism is caused when your cornea is not completely spherical in shape. Because our bodies are not perfect, astigmatism occurs in nearly everybody to some degree but for some, not to a degree that it causes blurring. Your cornea is naturally shaped like a sphere or the surface of a ball. Under normal circumstances, when light enters the eye, it bends evenly, creating a clear picture on the back of your eye. In a person with astigmatism, their eye is shaped more like the surface of a football and light entering the eye is bent more in one direction than the other. This causes only part of the picture to be in focus at any given time. Objects at any distance can appear blurry and wavy. For vision problems due to astigmatism, glasses or contact lenses, and sometimes even vision correction surgery are all possible treatments.
People with undetected astigmatism often have blurred vision which can be associated with fatigue and eyestrain. While these symptoms may not necessarily be the result of astigmatism, you should schedule an eye exam if you are experiencing one or more symptoms.
