Astigmatism is a very common eye condition that’s easily corrected by eyeglasses or contact lenses and on some occasions, surgery.
Astigmatism is usually associated with nearsightedness or farsightedness (myopia). Like nearsightedness and farsightedness, astigmatism is a refractive error. In other words, it is a problem in how your eye focuses light. This can cause blurry or distorted vision.
Astigmatism is not an eye disease or health problem. It does not cause blindness.
Astigmatism is caused when your eye is not completely round. Because our bodies are not perfect, astigmatism occurs in nearly everybody to some degree but for some, not to the degree that it causes blurring. Your eye is naturally shaped like a sphere. 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 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 in our Katy eye care center if you are experiencing one or more symptoms.
Astigmatism tends to develop in childhood. So regular eye exams from an optometrist can lead to early detection. Twenty-eight percent of children between the ages of 5 and 17 have astigmatism of 1 diopter or greater.
Once diagnosed, children will be spared the uncomfortable symptoms of astigmatism, such as headaches, eye strain and often squinting. Children tend to be unaware of these symptoms, so astigmatism often goes undiagnosed and untreated for years
Our eye doctor can diagnose astigmatism with a thorough eye exam. Astigmatism may occur in combination with other vision problems such as nearsightedness and farsightedness. Because astigmatism gets worse over time, visit our eye doctor whenever you notice changes in your vision. If you are serious about your sport or require specialty eyewear for your job or hobby, it’s worth scheduling a specialty eyewear fitting with your eye doctor.
