Astigmatism and Your Eyes (cont.)
In this Article
What Causes Astigmatism?
Astigmatism can be hereditary and is often present at birth. It can also result from pressure from the eyelids on the cornea, incorrect posture or an increased use of the eyes for close work.
What Are the Symptoms of Astigmatism?
Comment on this
People with undetected astigmatism often experience headaches, fatigue, eyestrain and blurred vision at all distances. 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.
How Are Astigmatisms Diagnosed?
Your optometrist or ophthalmologist can diagnose astigmatism with a thorough eye exam. Astigmatism may occur with other refractive errors such as myopia (nearsightedness) and hyperopia (farsightedness). Unfortunately, astigmatism often goes undetected in school-age children.
Because astigmatisms may increase slowly, you should visit your optometrist or ophthalmologist whenever you notice significant changes in your vision. Optometrists are trained specifically to examine the general health of the eyes and prescribe eyeglasses and contact lenses. Ophthalmologists provide total eye care, including exams, diagnosis, and treatment of disease through medication and surgery.
