Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.
Astigmatism is a very common vision condition. Most people have some degree of astigmatism. Slight amounts of astigmatism usually don't affect vision and don't require treatment. However, larger amounts cause distorted or blurred vision, eye discomfort and headaches.
Astigmatism frequently occurs with other vision conditions like nearsightedness (myopia) and farsightedness (hyperopia). Together these vision conditions are referred to as refractive errors because they affect how the eyes bend or "refract" light.
The specific cause of astigmatism is unknown. It can be hereditary and is usually present from birth. It can change as a child grows and may decrease or worsen over time.
A comprehensive optometric examination will include testing for astigmatism. Depending on the amount present, Drs. John and Katie Mason can provide eyeglasses or contact lenses that correct the astigmatism by altering the way light enters your eyes.

Keeping Your Eyes Healthy: Get regular comprehensive dilated eye exams
Getting a dilated eye exam is the only way to catch eye diseases early, because with many, there are no warning signs.
You might think your vision is in good shape or that your eyes are healthy, but visiting Dr. Mason for a comprehensive dilated eye exam is the only way to be completely certain. When it comes to common vision problems, many people don’t realize their vision could be improved with glasses or contact lenses. In addition, many common eye diseases such as glaucoma, diabetic eye disease, and age-related macular degeneration often have no symptoms. A dilated eye exam is the only way to detect these diseases in their early stages. Talk to your eye care professional about how often you should have one.
During a comprehensive dilated eye exam, drops are placed in your eyes to dilate, or widen, the pupil. Dr. Mason uses a special magnifying lens to examine your retina and look for signs of damage and other eye problems. After the examination, your close-up vision may remain blurred for several hours.
